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/(4pi epsilon_0 L)`

B

`q/(2pi epsilon_0L)`

C

`q/(pi epsilon_0L)`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
D
Electric flux for any surface is defined as
`phi= int E.ds`
Flux through each face =`1/6 q/e_0` So, flux through the face `ABCD,=1/6 q/e_0`

The options (A), (B) and (C) are dimensionally incorrect, so they cannot be answers
