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.

a> charge enclosed is zero, E is zero. Gauss Law.

b. the E is due to the center charge ONLY (Gauss Law) E=kq/.09^2

For a), we're looking at outside of the shell which is not enclosed in the spherical shell.

A -7 nC point charge is located at the centre of conducing spherical shell.The shell has inner raduis 2m and outer raduis 4m and a charge of + 6 nC

Calculate the charge on the sphere outer surface ?

•A + 9.0 nC point charge is located in the center of a thick conducting spherical shell. The shell has an inner radius of 1.0 m, an outer radius of 1.4 m, and a charge of -5.0 nC. What is the magnitude of the electric field at r = 0.5 m?
