If the electric flux entering and leaving an enclosed surface respectively is `phi_1` and `phi_2`, the electric charge inside the surface will be

A

`(phi_(1)+phi_(2))epsilon_(0)`

B

`(phi_(2)-phi_(1))epsilon_(0)`

C

`(phi_(1)+phi_(2))//epsilon_(0)`

D

`(phi_(2)-phi_(1))//epsilon_(0)`

Text Solution

Verified by Experts

The correct Answer is:
B

`varphi_(n et) = (1)/(epsilon_(0))xxQ_(enc)implies Q_(enc)=(varphi_(2)-varphi_(1))epsilon_(0)`
