An electric charge q is placed at the centre of a cube of side l. The electric flux through one of its faces will be

A

`(6q)/(epsilon_(0))`

B

`(q)/(epsilon_(0))`

C

`(q)/(6epsilon_(0))`

D

`(2q)/(3epsilon_(0))`

Text Solution

Verified by Experts

The correct Answer is:
C
A cube have 6 faces so flux through one face is given by gauss law
`phi=(q)/(epsilon_(0))` for the cube
`rArrphi=(q)/(6epsilon_(0))` (for each faces)
