Electric charges are distributed in a small volume.The flux of the electric field through a spherical surface of radius `1`m surrounding the total charge is `100V -m`.The flux over the concentric sphere of radius `2`m will be:

Options

A. 25 V - m
B. 50 V - m
C. 100 V - m
D. 200 V - m

Answer

C

Explanation

Flux does not depend on the size and shaps of the close surface , and so, it remains same .
