Class XII Physics :: How to prepare well in advance?

Learn thoroughly the first time you learn a new concept. Suppose, the topic Kirchhoff’s laws is taught in class. Revise the topic the same day yourselves. Keep a paper and pen while you revise and jot down whatever you feel important. Please note that you cannot memorize derivations by reading. Write and practice the derivations.…… Continue reading Class XII Physics :: How to prepare well in advance?

Practice Numericals from Electrostatics

Four point charges +5 mC, +2 mC, +10mC and +2 mC are kept at the corners of a square of side 10 cm. A charge q=+1mC is placed at its centre. Find the net force on q. Calculate the distance between two prorons such that the electrostatic force between them is equal to the weight…… Continue reading Practice Numericals from Electrostatics
