a cathod ray passing through electric field in 3kw n/c
Cathode Rays consist of fast moving electrons which are negatively charged particles.Under the influence of electric field, the electron will experience a force towards the positive electrode and thus they will get deflected towards it. Force on charged particles due to electric field is F= qE ( F = force , q = Charge , E = Electric Field).
why this models ppr is not in english
Kindly clarify your question properly so that we could provide you a proper answer , you are asking that why this model paper is not in English but you didn't mention the name of that model paper.
Actually first of all model paper will be in Hindi if this is a Hindi subject and if you want english version of any subject (if available) then you will have to buy by saying to the seller that you want in English language.
Best of luck.
