24 A uniform electric field of magnitude 1.1×104 N/C is perpendicular to a square sheet with sides 2.0 m long. What is the electric flux through the sheet?

Explanation:

The electric flux through a certain surface is given by (for a uniform field):

where:

E is the magnitude of the electric field

A is the area of the surface

is the angle between the direction of the field and of the normal to the surface

In this problem, we have:

is the electric field

L = 2.0 m is the side of the sheet, so the area is

, since the electric field is perpendicular to the surface

Therefore, the electric flux is
