A charged rod is brought near an initially neutral metal sphere without touching it.

When the sphere is grounded (earthed), there is an electric current for a short time from the sphere to the ground.

The ground connection is then removed.

What are the charge on the rod and the charge induced on the sphere when the connection is removed?
