Question: In copper, about one electron per atom is free to move about. A copper penny has a mass of 3 g. (a) What percentage of

In copper, about one electron per atom is free to move about. A copper penny has a mass of 3 g.

(a) What percentage of the free charge would have to be removed to give the penny a charge of 15 μC?

(b) What would be the force of repulsion between two pennies carrying this charge if they were 25 cm apart? Assume that the pennies are point charges.
