The electric flux through the surface

Options

A. in fig, (iv) is the largest
B. in fig, (iii) is the least
C. in fig (ii) is same as a fig (iii) but is smaller than that in Fig (iv).
D. is the same for all the figures.

Answer

D

Explanation

The electric flux through a surface depends only on amount of charge enclosed by the surface. It does not depend on size and shape of the surface, as per Gauss's theorem in electrostics. Therefore, electric flux through the surface is the same for all the figures, chose (d) is correct.
