A charge Q = 50.0nC is located 0.30 m from point A and 0.50 m from

A charge Q = ˆ’ 50.0nC is located 0.30 m from point A and 0.50 m from point B.
(a) What is the potential at A?
(b) What is the potential at B?
(c) If a point charge q is moved from A to B while Q is fixed in place, through what potential difference does it move? Does its potential increase or decrease?
(d) If q = ˆ’ 1.0nC, what is the change in electric potential energy as it moves from A to B? Does the potential energy increase or decrease?
(e) How much work is done by the electric field due to charge Q as q moves from A to B?
