What is potential difference, Physics

Assignment Help:

A pith ball weighing 3.0 x 10-2N carries a charge of -1.0 x 10-6 C.

The pith ball is placed among two large, parallel, metal plates that are divided by 0.050 m.

What is the potential difference, ΔV, that must be applied in order to suspend the pith ball between the plates?
