Question

A charged particle q is placed at the centre O of cube of length L (A B C D E F G H). Another same charge q is placed at a distance L from O. Then the electric flux through ABCD is

• A. $q/4\pi \in_0 L$
• B. zero
• C. $q/2\pi \in_0 L$
• D. $q/3\pi \in_0 L$

Answer 1

Answer: (B)

zero

Answer 2

The flux for both the charges exactly cancels the effect of each other.
