A square surface of side `L m` is in the plane of the paper. A uniform electric field `vec(E )(V//m)`, also in the plane of the paper, is limited only to the lower half of the square surface (see figure). The electric flux in `SI` units associated with the surface is:

A

Zero

B

`EL^2`

C

`EL^2//(2 epsilon_0)`

D

`EL^2//2`

Text Solution

Verified by Experts

The correct Answer is:
A
`phi =0`
Because no. of field line entering
= no. of field lines leaving. `[ theta = 90^@]`
