The electric field intensity at a point 2m from the surface of a uniformly charged conducting sphere is 1920 N/C. At a point 4m from its center, the electric field intensity is 3000 N/C.
a.) Determine the radius of the sphere. Determine the electric field intensity at a point:
(b.) 2m from its center,
(c.) 6m from its center, and
(d.) 4m from its surface.
