Question

Two thin spherical shells, one with radius R and the other with radius 2R, surround an isolated charged point particle. The ratio of the number of field lines through the larger sphere to the number through the smaller is​

Answer 1

both have same number of electric field line

Explanation:

because electric filed line passing through surface which is also called electric flux is independent on area or size of closed surface

electric flux only depends on the magnitude of charge enclosed and the medium...
