Franklins Bells, Physics

(Assume the metallic ball is spherical with a diameter d = 2.5 cm. Let''s also
assume it is made out of nickel, which has a density of roughly 9 g/cm
.) After it first
touches the right-hand bell, the little ball will pick up some charge, which will spread
(pretty) uniformly over its entire surface. A reasonable number for the magnitude of
this charge would be about 0.03 ?C. Given these numbers, will the bell become
discharged if the ball touches it once or twice? Why or why not?
