Consider an insulating sphere of radius 5 cm surrounded by a conducting sphere of inner radius 22 cm and outer radius 25 cm. Furthermore, suppose that the electric field at a point 13 cm from the center is measured to be 1540 N/C radially inward while the electric field at a point 44 cm from the center is 90 N/C radially outward.

1. Find the charge on the insulating sphere. Answer in units of C.

2.Find the net charge on the conducting sphere. Answer in units of C.

3.Find the total charge on the inner surface of the hollow conducting sphere. Answer in units of C.

4. Find the total charge on the outer surface of the hollow conducting sphere. Answer in units of C.
