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 fig.(iii) but is smaller than fig.(iv)
D. Is the same for all the figures.

Answer

D

Explanation

Gauss' law of electrostatics state that the total of the electric flux out of a closed surface is equal to the charge enclosed decided by the permittivity i.e., Q electric `=(Q)/(epsi_(0))` Thus, electfi flux through a surface doesn't depend on the shape, size or area of a surafce but it depends on the number of charges enclosed by the surface
So, here in this question, al the figures same electric flux as all of them has single positive charge.
