Answer 1

Answer:

Explanation:

A rod is brought close to the sphere, the free electron in the sphere move away due to deficit of electrons. The process of change distribution stops when the net force on the free electron inside the metal is less.

When we connect the sphere to the ground electron will fow to the ground while the charge will remain on the sphere.
