Question

Suppose a conducting sphere, radius r2, has a spherical cavity of radius r1 centered at the sphere's center. At the center of the sphere is a point charge -4Q. Assuming the conducting sphere has a net charge +Q determine the electric field,magnitude and direction, in the following situations:

a) From r = 0 to r = r1.

b) From r = r1 to r = r2.

c) Outside of r = r2

d) find the surface charge density (charge per surface area) conductor, respectively.

the inside and outside surfaces of the on
