Problem
A metal sphere of radius 4.0 cm is isolated in space and initially carries a charge of +8.0 nC. It is then briefly connected to Earth (ground) with a conducting wire, after which the wire is removed. How much charge remains on the sphere?
(a) +8nC
(b) An amount that depends on the sphere’s radius
(c) 0nC
(d) −8nC
