a) A point charge of 5.5 µC is located at the center of a spherical shell of radius 18 cm, which has a charge −5.5 µC uniformly distributed on its surface. Find the electric fieldfor all points outside the spherical shell. The Coulomb constant is 8.98755 ×10^9 N m^2/C^2. Answer in units of N/C. b) Find the electric field for a point inside the shell a distance 9 cm from the center. Answer in units of N/C.
