Solution:-

\begin{aligned} &\vec{a}+\vec{b}+\vec{c}= \\\\ &=\overrightarrow{A C}+\vec{c} \\\\ &=\overrightarrow{A C}+\overrightarrow{C A} \end{aligned}
\begin{aligned} &=\overrightarrow{A C}-\overrightarrow{A C} \\\\ &=0 \\\\ &\vec{a}+\vec{b}+\vec{c}=0 \end{aligned}

Algebra of Vectors exercise Fill in the blanks question 2

Answer:- $\overrightarrow{A C}=\vec{a}+\vec{b}, \overrightarrow{B D}=\vec{b}+\vec{a}$
Hint:- To solve this equation ,we use right angle triangle formula.
Given:- In a parallelogram $\mathrm{ABCD} \text { If } \overrightarrow{A B}=a \text { and } \overrightarrow{B C}=b \text {, then } \overrightarrow{A C}=\ldots \text { and } \overrightarrow{B D}=\ldots$
Solution:- In $\Delta ABC$

According to right triangle
\begin{aligned} &\overrightarrow{A B}+\overrightarrow{B C}=\overrightarrow{A C}\\\\ &\vec{a}+\vec{b}=\overrightarrow{A C}\\\\ &\overrightarrow{A C}=\vec{a}+\vec{b}\\\\ &\text { In } \Delta B D A \end{aligned}
According to right triangle
\begin{aligned} &\overrightarrow{A B}+\overrightarrow{B D}=\overrightarrow{A D} \\\\ &\vec{a}+\overrightarrow{B D}=\vec{b} \\\\ &\overrightarrow{B D}=\vec{b}-\vec{a} \end{aligned}

Algebra of Vectors exercise Fill in the blanks question 3

Answer:-$0$
Hint:- We use the section formula for finding coordinates of centroid.
Given:- If $\vec{a}, \vec{b}, \vec{c}$ are the position vectors of the vectors of a triangle having its centroid at the origin then $\vec{a}+\vec{b}+\vec{c}=\ldots .$
Solution: Here the coordinates of $D = (a+b)/2$

$\begin{gathered} \frac{m \vec{b}+n \vec{a}}{m+n} \\\\ \frac{m}{n}=2 \end{gathered}$
\begin{aligned} &\frac{2\left(\frac{\vec{a}+\vec{b}}{2}\right)+1(\vec{c})}{3} \\\\ &=G\left(\frac{\vec{a}+\vec{b}+\vec{c}}{3}\right) \end{aligned}
Here, given that centroid is at the origin $(a + b + c)/3=0$
Therefore, $a+ b+ c =0$

Algebra of Vectors exercise Fill in the blanks question 4

Answer:-$0$
Hint:- To solve this equation we will make triangle, then we will find modulus.
Given:-If $a, b, c$ are the positive vectors of vertices of an equilateral triangle having its circumcentre at the origin, then $\vec{a}+\vec{b}+\vec{c}=\cdots \cdots \cdots$
Solution:-$\overrightarrow{O C}=\vec{c}$

Centroid of triangle $= (a+b+c)/3$
For an equilateral triangle the circumcentre coincide with the centroid. Therefore,
\begin{aligned} &\frac{\vec{a}+\vec{b}+\vec{c}}{3}=0 \\\\ &\vec{a}+\vec{b}+\vec{c}=0 \end{aligned}

Algebra of Vectors exercise Fill in the blanks question 5

Hint:- To solve this question we use $\vec{b}=\lambda \vec{a}$ where $\lambda$ is constant.
Given:- If the vector $\vec{a}=\hat{i}-2 \hat{j}+3 \hat{k} \text { and } \vec{b}=3 \hat{i}-6 \hat{j}+m \hat{k}$ are collinear then $m= ----$
\begin{aligned} &\vec{a}=\hat{i}-2 \hat{j}+3 \hat{k} \\\\ &\vec{b}=3 \hat{i}-6 \hat{j}+m \hat{k} \end{aligned}
Using $\frac{a_{1}}{a_{2}}=\frac{b_{1}}{b_{2}}=\frac{c_{1}}{c_{2}}$

Then, $\frac{1}{3}=\frac{-2}{-6}=\frac{3}{m}$

$\frac{1}{3}=\frac{3}{m}$
Therefore, $m = 9.$

Given:-Vector of magnitude $21$ units in the direction of the vector $3 \hat{i}-6 \hat{j}+2 \hat{k}$
Solution:- we have Vector of magnitude $21$ units in the direction of the vector $3 \hat{i}-6 \hat{j}+2 \hat{k}$
\begin{aligned} &=\frac{3 \hat{i}-6 \hat{j}+2 \hat{k}}{\sqrt{9+36+4}} \\\\ &\hat{A}=\frac{3 \hat{i}-6 \hat{j}+2 \hat{k}}{\sqrt{49}} \end{aligned}
\begin{aligned} &\hat{A}=\frac{3 \hat{i}}{7}-\frac{6 \hat{j}}{7}+\frac{2 \hat{k}}{7} \\\\ &\vec{B}=|B| \hat{A} \end{aligned}
\begin{aligned} &\vec{B}=21\left[\frac{3 \hat{i}}{7}-\frac{6 \hat{j}}{7}+\frac{2 \hat{k}}{7}\right] \\\\ &\vec{B}=9 \hat{i}-18 \hat{j}+6 \hat{k} \end{aligned}

Solution:- Let $a, b, c$ are the position vectors of $AB, BC, and \; CA$ respectively.
$\overrightarrow{A B}+\overrightarrow{A C}=k \overrightarrow{A D}$

\begin{aligned} &\vec{b}-\vec{a}+\vec{c}-\vec{a}=k\left[\frac{\vec{b}+\vec{c}}{2}-\vec{a}\right] \\\\ &\vec{b}+\vec{c}-2 \vec{a}=k \frac{(\vec{b}+\vec{c}-2 \vec{a})}{2} \\\\ &\mathrm{k}=2 \end{aligned}

Algebra of Vectors exercise Fill in the blanks question 8

Answer:- $\frac{1}{3}, \frac{-2}{3}, \frac{2}{3}$

Given:-A vector of magnitude 6; making angle $\frac{\pi }{4}$ with x-axis; $\frac{\pi }{3}$ with y axis and an acute angle with z axis
Solution:-we have $|\vec{a}|=6$
\begin{aligned} &\text { So } l=\cos \alpha=\frac{\sqrt{2}}{2} \\\\ &m=\cos \beta=\frac{1}{2} \\\\ &n=\cos \gamma=\cos \theta \end{aligned}

We know that $l^{2}+n^{2}+m^{2}=1$

\begin{aligned} &\left(\frac{\sqrt{2}}{2}\right)^{2}+\left(\frac{1}{2}\right)^{2}+n^{2}=1 \\\\ &\frac{2}{4}-\frac{1}{4}+n^{2}=1 \\\\ &\frac{3}{4}+n^{2}=1 \end{aligned}
\begin{aligned} &n^{2}=1-\frac{3}{4}=\frac{4-3}{4}=\frac{1}{4} \\\\ &n=\pm \frac{1}{2} \\\\ &\hat{a}=l \hat{i}+m \hat{j}+n \hat{k}=\frac{1}{\sqrt{2}} \hat{i}+\frac{1}{2} \hat{j}+\frac{1}{2} \hat{k} \end{aligned}
\begin{aligned} &\hat{a}=|\hat{a}|(\hat{i}+m \hat{j}+n \hat{k}) \\\\ &=6\left(\frac{1}{\sqrt{2}} \hat{i}+\frac{1}{2} \hat{j}+\frac{1}{2} \hat{k}\right) \\\\ &=3 \sqrt{2} \hat{i}+3 \hat{j}+3 \hat{k} \end{aligned}

Algebra of Vectors exercise Fill in the blanks question 10

Answer:- $x+y+z=2$
Hint:-To solve this equation, we use substitute method
Given:- If the vector $\vec{a}=2 \hat{i}-(y+z) \hat{j}+5 \hat{k} \text { and } \vec{b}=(x+y) \hat{i}+3 \hat{j}+(z+x) \hat{k}$ are then $x+y+z=$____
Solution:- $\vec{a}=\vec{b}$
$2 \hat{i}-(y+z) \hat{j}+5 \hat{k}=(x+y) \hat{i}+3 \hat{j}+(z+x) \hat{k}$
Comparing we get
$\begin{array}{ll} x+y=2 & \text {...( } i) \\\\ -(y+z)=3 & \text {...(ii) } \\\\ , z+x=5 & \text {...(iii) } \end{array}$
From eq (ii) we make y the subject to the equation
Substitute for $y=-3-z$ in the equation(i)
\begin{aligned} &x-3-z=2 \quad ......(iv)\\ \\ &x-z=5 \end{aligned}
Solving eq(iii) & (iv)
\begin{aligned} &z+x+x-z=5+5 \\\\ &2 x=10 \\\\ &x=5 \end{aligned}
Put the values of x in eq(iii)
\begin{aligned} &z+5=5 \\\\ &z=0 \end{aligned}
Put the values of z in eq(ii)
\begin{aligned} &\mathrm{y}=-3 \\\\ &\text { so, } \mathrm{x}+\mathrm{y}+\mathrm{z}=5+(-3)+0 \\\\ &\quad=5-3 \\\\ &\quad=2 \end{aligned}

Solution:-here
\begin{aligned} &\overrightarrow{A B}=\vec{B}-\vec{A}=\vec{b}-\vec{a} \\\\ &\overrightarrow{A C}=\vec{C}-\vec{A}=\vec{c}-\vec{a} \end{aligned}
We have $\overrightarrow{A C}=3 \overrightarrow{A B}$
$|\overrightarrow{A B}|=x$
Then $\overrightarrow{A C}=3 x$
$\frac{A C}{B C}=\frac{m}{n} \rightarrow \bar{c}=\frac{m \vec{b}-n \vec{a}}{m-n}$
External dimension
$\bar{c}=\frac{3 \vec{b}-2 \vec{a}}{3-2}=\frac{3 \vec{b}-2 \vec{a}}{1}=3 \vec{b}-2 \vec{a}$

## RD Sharma Chapter wise Solutions

1. What are the norms of the vector?

The length of the vector is referred to as the vector  or the vector's magnitude.  The length of a vector is a non-negative number that describes the extent of the vector in space,  and is sometimes referred to as the vectors of magnitude or the norm

2. What are the directions of a vector?

The direction of a vector is the orientation of the vector,  that is,  the angle it makes with the x-axis.

3. What is the sum of vectors called?

The sum of two or more vectors is called the resultant.  The resultant of two vectors can be found using either the parallelogram method or the triangle method.
