A spherical conductor has a radius of 14.0 cm and a charge of 68.0 µC. Calculate the electric field and the electric potential at the following distances from the center.
(a) r = 8.0 cm
Electric field= ? MN/C
Electric potential= ? MV
(b) r = 38.0 cm
Electric field= ? MN/C
Electric potential= ? MV
(c) r = 14.0 cm
Electric field= ? MN/C
Electric potential= ? MV
