A point charge q is placed at the geometric centre of one of the faces of a cubical surface due to the charge is :

A

`q/(epsilon_(0))`

B

`q/(2epsilon_(0))`

C

`q/(4epsilon_(0))`

D

zero

Text Solution

Verified by Experts

The correct Answer is:
B, C, D

If we construct an identical to right of this cube (ABCD) s.t face ABCD is common to both cubes , we have a closed Gaussion surface . Now symmetry of aarangment ensures that flus through each of two cubes is half of total value `q/(epsilon_(0))` .
