A research Van de Graaff generator has a 3.80 m diameter metal sphere with a charge of 1.06 mC on it.
(a) What is the electric potential on the surface of the sphere?
V
(b) At what distance from its center is the potential 3.00 MV?
m
(c) An oxygen atom with three missing electrons is released near the surface of the Van de Graaff generator. What is its kinetic energy in MeV at the distance determined in part (b)?
MeV
