Answer to Question #327142 in Physics for Jay

Question

A uniform electric field E = 5000 N/C passing through a flat square area A = 2m2. Determine the electric flux. Note: The angle between the electric field direction and a line drawn perpendicular to the area is 60 degree.

Answer 1

The electric flux is given by

$$\phi=EA\cos\theta$$ $$\phi=5000*2*\cos60^\circ=5000\:\rm N\cdot m^2/C$$
