Acharge is added to a small sphere by touching it with a probe that was raised to a 3000 v potential. the spheres used had a diameter of 3.7 cm’s and raised the entire surface to an electric potential of 3000 v’s. using some reasonable assumptions:
(a)how much charge was collected on the surface of these spheres
(b)what is the force (in newton’s) between these two spheres when they were 10 cm’s apart.
(c)assuming one is charged to +3000 v, and the other to -3000v, what would the capacitance be for this arrangement? (explain justifications for any simplifications)
