A point charge q is placed at the centre of a cube of side length L . The electric flux emerging from the cube is……

A

`q/e_0`

B

zero

C

`(6ql)^2/e_0`

D

`q/(6L^2 e_0)`

Text Solution

Verified by Experts

The correct Answer is:
A
Here given closed surface, enclosed charge q . Hence whatever electric flux is emanating from charge q. Same amount is passing through surrounding enclosing surface (here surface of cube). This amount is given by Gauss.s law.
`phi=q/e_0`
