A fellow scientist heard that a Van de Graaff generator built 70 years ago could collect 5.0 C of charge on its dome, which had a radius of 1.1 m, and has challenged you to do the same. You plan to use the same dome with the same radius and the belt you plan to use is 200 mm wide and 10.0 m long (5.0 m to go up to the dome, and 5.0 m to come back down). Charging the belt gives it a surface charge density of 65 μC/m2 . Assume that the belt is being charged at a distance of half of the belt length from the center of the dome.

How much force must your motor be able to exert on the belt in order to accomplish your goal?
