A soild conducting sphere of radius 10.0cm has a total positive charge of 8.00 uC. Thus, the charge is uniformly distributed on the sphere.

(a) Find the direction and the magnitude of the electric field at 15.0 cm from the center of the center.

(b) Find the direction and the magnitude of the electric field at 5.00 cm from the center of the sphere.

(c) Calculate the electric potential at 15.0 cm from the center of the sphere relative to the electrical potential far away.

(d) Calculate the electric potential at 5.0 cm from the center of the sphere relative to the electrical potential far away.
