Question

A point charge q= 2 C is at the center of a sphere ofradius 0.5 m.
a) What is the surface area of the sphere? b) What is the magnitude of the electric field at points onthe surface of the sphere? c) What is the flux of the electric field due to the pointcharge through the sphere? d) What is the net flux through a cube of side 1 m thatencloses the sphere?
a) What is the surface area of the sphere? b) What is the magnitude of the electric field at points onthe surface of the sphere? c) What is the flux of the electric field due to the pointcharge through the sphere? d) What is the net flux through a cube of side 1 m thatencloses the sphere?

Explanation / Answer

Electric field will be equal to that atdistance d = 0.5 m E = kq/r2 = 72 kN/C flux through sphere = 0    as no charge in metallic material flux in cube of 1m side = flux of charge flux = q/ = 0.226 *106 Nm2/C
