A square surface of side L in the plane ...

A square surface of side L in the plane of the paper is placed in a uniform electric field E acting along the same. Plane at an angle ` theta ` with the horizontal side of the square as shown in. The electric flux linked to the surface is

A

` EL^(2) sin theta `

B

zero

C

`EL^(2) `

D

` EL^(2) cos theta`

Text Solution

Verified by Experts

The correct Answer is:
B
since ` oversettoE ` is in the plane of Square, hence `oversetto E and ` area vector ` oversetto A ` are inclined at an angle of ` 90 ^(@) ` and electric flux ` oversetto E. oversetto oA =0. `
