7. Calculate the work that must be done on charges to bring them from infinity to charge a spherical shell of radius R to a total charge Q. 8. How many electrons should be removed from an initially uncharged spherical conductor of radius 0.300 m to produce a potential of 7.5 kV at the surface? The charge of the electron is 1.6 x 10-19 C.
