A flat sheet is in the shape of a rectangle with sides of lengths 0.400 m and 0.600 m. The sheet is immersed in a uniform electric field of magnitude 90.0 N/C that is directed at 20 degrees from the plane of the sheet. Find the magnitude of the electric flux through the sheet. a. For what angle between the normal to the sheet and the electric field is the magnitude of the flux through the sheet (i) largest and (ii) smallest
The magnitude of electric flux is found to be "6.1 N.m²/C".
Solution:
The electric flux can be given by the following formula:
∅ = EACosθ
where,
∅ = electric flux
E = Electric field = 73.9 N/C
A = Area of the plate = (0.4 m)(0.6 m) = 0.24 m²
θ = angle between normal to area and electric field lines = 90° - 20° = 70°
Therefore,
∅ = 73.9 * 0.24 * Cos70°
∅ = 6.1 N.m^2/C
What is electric flux?
Although an electric field cannot flow by itself, electric flux in electromagnetism is a measure of the electric field passing through a certain surface. It is a technique of expressing how strong an electric field is at any distance from the charge that is producing it.
