Question
I'm stuck on part (d). For (a), I got -5000 V,for (b) I got -1800 V, and for (c) 3200 V. I don't know ifthose are the right answers, but I tried to do as much as I could.Any help would be greatly appreciated!A charge Q=-50.0 nC is located 0.30 m from point A and 0.50 m from pointB. (a) What is thepotential at A? (b) What is the potential atB? (c) If a pointcharge qismoved from Ato Bwhile Qisfixed in place, through what potential difference does it move (d)Does its electric potential energy increase or decrease, by howmuch?

Explanation / Answer
Hi, For (d) The electric potential energy at point A is UA=VAq = (-5000V)q The electric potential energy at point B is UB =VBq = (-1800V)q Then change in potential energy is U =UB-UA = [ (-1800V)q] - [(-5000V)q] = (3200V)q Increase or decrease of potential energy depends on the charge ofthe point charge q. If q is positive, then there is increase in potential energy of(3200V)q If q is negative, then there is decrease in potential energy of(3200V)q Hope this helps you
