The total electric flux for the following closed surface which is kept inside water ………. .

A

`(80q)/(varepsilon_0)`

B

`q/(40varepsilon_0)`

C

`q/(80varepsilon_0)`

D

`q/(160varepsilon_0)`

Text Solution

Verified by Experts

The correct Answer is:
B
`phi = q_(net)/epsilon_0`
`q_(net)=-q+q+2q=2q`
Relative permittivity of water = 80
`:. Phi = q/(epsilon_repsilon_0)=(2q)/(80epsilon_0)=q/(40epsilon_0`
