    The Maharashtra HSC Physics answer key 2025 only covers the objective section of the paper, specifically the 1-mark and 2-mark questions. The remaining sections, which assess the candidate's writing style and content, do not have a corresponding answer key. Section A of the Maharashtra physics exam paper consists of two parts: Question 1, containing 10 multiple-choice questions, and Question 2, containing 8 very short answer questions. The answers to these Maha 12th physics questions are provided below.

    Section A Question 2: HSC Physics Very Short Answer Type Questions

    Sub Question Number

    Answers

    1. At what temperature the surface tension of the liquid becomes zero

    At zero (0) Kelvin

    2. Define self-inductance?

    Self-inductance is a property of an electrical conductor, such as a coil of wire, where a changing current in the conductor induces a voltage in the same conductor. This induced voltage opposes the change in current that caused it, a phenomenon known as self-induction

    3. What is work done by an external uniform magnetic field perpendicular to the velocity of a moving charge?

    The work done by an external uniform magnetic field perpendicular to the velocity of a moving charge is zero.

    4. What do you mean by a thermodynamic system?

    A thermodynamic system is a defined region of space or matter that is studied in thermodynamics. It's a specific portion of the universe that we choose to focus on, separated from its surroundings by a boundary

    5. What is the value of B called, when H= 0 in the hysteresis loop?

    Retentivity

    6. State the formula for the angle of banking

    The formula for the angle of banking (θ) is:

    tan θ = v² / (rg)

    Where:

    • θ is the angle of banking (the angle at which the road is inclined)
    • v is the speed of the vehicle
    • r is the radius of the curve
    • g is the acceleration due to gravity

    7. Calculate the electric field intensity at a point just near the surface of the charged plane sheet, measured from its midpoint.

    The electric field intensity (E) at a point just near the surface of a charged plane sheet, measured from its midpoint, is given by:

    E = σ / (2ε₀)

    1000084261

    8. Find the Kinetic Energy of 1 litre of an ideal gas at STP

    The kinetic energy of 1 liter of an ideal gas at STP is approximately 150 Joules.


    How to Calculate Maharashtra HSC Physics Answer Key Marks?

    To pass the Maharashtra HSC exams, students must achieve a minimum score of 35%, according to the Maharashtra Board's qualifying criteria. While the Maharashtra HSC physics answer key allows students to estimate their scores, the official passing mark remains 35%. The steps for calculating the score using the Maharashtra HSC physics answer key are outlined below.

    • Obtain the Maharashtra Board Physics Answer Key: Download the official Maharashtra HSC Physics answer key from the Maharashtra State Board of Secondary and Higher Secondary Education (MBSHSE) website.

    • Compare Your HSC Physics Answers: Carefully compare your Maha 12th physics answers on your exam paper with the correct answers provided in the official answer key.

    • Count Correct Answers:

    • MCQs: For each MCQ you answered correctly, award yourself the marks allotted to that question (usually 1 mark).

    • Very Short Answer Questions: Similarly, for each very short answer question you answered correctly, award yourself the marks allotted (usually 1 or 2 marks, check the paper pattern).

    • Calculate Total Score for Physics Objective Section: Add up the marks you awarded yourself for all the correct MCQs and very short answer questions. This is your estimated score for the objective section of the paper.

    • Subjective Section (No Answer Key): You cannot calculate your score for the subjective section using a Maharashtra physics answer key. This section is graded based on the content, understanding, presentation, and overall quality of your answers. Experienced examiners will evaluate these answers based on established criteria. You will have to wait for the official Maharashtra 12th results for this part.

    • Estimated Total Score (Partial): Add your estimated score from the objective section to your estimated score for the subjective section. Since you can not precisely calculate the subjective section, this final number will be an approximation of your total score.
