How much charge is on the inside surface of hollow sphere

Reference no: EM13679143

A 3.50nC point charge is placed at the centre of a hollow metal sphere that has an inner radius 4.90cm and an outer radius 12.0cm. The metal sphere itself is charged to 7.00nC.

1. How much charge is on the outside surface of the hollow sphere?

2. How much charge is on the inside surface of the hollow sphere?

3. What is the magnitude of the electric field at a distance 16.9cm from the centre?

4. What is the magnitude of the electric field at a distance of 2.45cm from the centre?

5. What is the magnitude of the electric field at a distance of 8.45cm from the centre?
