The work done by an external force to move a -8.4*10^-6C charge from point a to point b is 1.9*10^3J. If the charge was started at rest and has 4.81*10^4J of KE when it reach pt. B, whats the change in PE of the charge?
W=change in U
The Attempt at a Solution
I tried a few things but im just not sure how to approach this problem. I attempted V=Uelect/q and W= change in U, U=qV.... just looking for some direction, thanks!
