Homework Statement
Part A - (Already solved)
The electric potential at point A is 1800V.
Part B -
What is the potential energy of an electron at point A in the figure?
Point A is .01m away from a charge of +2nC
Homework Equations
V=Uq
U = (Kq1q2)/r
The Attempt at a Solution
I think the problem is, is that I am confused about the difference between electric potential and potential energy. This problem shouldn't be difficult.
So I tried the second equation
U = (9.00*10^9)(1.6*10^-19)(2*10^-9)/.01
U = 2.88*10^-18
But that isn't the answer...I don't know what equation I should use or what I am doing wrong.
