An electric dipole is placed at the centre of a sphere. The flux passing through the surface of the sphere is..........

A

Infinity

B

Zero

C

Cannot be found

D

`(2q)/epsilon_(0)`

Text Solution

Verified by Experts

The correct Answer is:
B
The total charge on electric dipole is
`sumq = +q +(-q)=0`
The flux passing through the surface of the sphere according to Gauss.s theorem,
`phi = (sumq)/epsilon_(0) =(+q-q)/epsilon_(0) =0`
