Question

A square surface of side L meteres is in the plane of the paper a uniform electric field E volt/m also in thr plane of the paper is limited only to the lower half of the square surface the electric flux in si unit associated with the surface is

Answer 1

Answer:

I am host and you are my dost

Answer 2

Answer:

The electric flux linked to the surface is given by:

ϕ E= E.d A

The angle between the area vector and the field lines is 90 °.

Thus,

ϕ E =EAcosθ=0

Also,

As, there is no field line crossing the surface, the electric flux linked to the surface will be zero.
