A point charge of 2.4 μC is located at
the center of a spherical shell of radius 17 cm, which has a charge −2.4 μC uniformly distributed on its surface. Given:
ke = 8.98755 109 Nm2/C2 .

a)Find the electric field for all points outside the spherical shell.

b)Find the electric field for a point inside the shell a distance 9 cm from the center.

The answer for b is not zero, btw.
