A charge of q = +10-7 C is uniformly distributed on a spherical shell of radius 12 cm.
(a) What is the magnitude of the electric field just outside and just inside the shell?
kV/m (outside)
kV/m (inside)
(b) What is the magnitude of the electric potential just outside and just inside the shell?
V (outside)
V (inside)
(c) What is the electric potential at the center of the shell?
V
(d) What is the electric field at that point?
