A charge Q = 5.0 nC is located 0.30m from point A and 0.50m from point B.
(a) What is the potential at point 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 = -1.0 nC, what is the change in potential energyas it movesfrom A to B? Does it increase or decrease?
(e) How much work is done by the electrical field due to charge Q as q moves from A to B?
