A Gausisan surface in the figure is shown by dotted line.
The electric field on the surface will be

A

(a) due to `q_1` and `q_2` only

B

(b) due to `q_2` only

C

(c) `zero`

D

(d) due to all

Text Solution

Verified by Experts

The correct Answer is:
D
The flux through the Gausisan surface is due to the charges inisde the Gausisan surface. But the electric field on the Gausisan surface will be due to the charges present in the isde the Gausisan surface and outisde it. It will be due to all the charges.
