The force between the spheres will increase by a factor of 2.

The metal sphere gains electrons and becomes negatively charged.

Electrons from the metal sphere move to the glass rod, leaving the sphere with a net positive charge.

The metal sphere remains neutral.

The metal sphere becomes magnetized.
