Question

The work done by an external force to move a -8.50 microCcharge from point a to point b is1.90×103 J. If the charge was started from rest and had4.80×104 J of kinetic energy when itreached point b, what must be the potential differencebetween a and b? If the charge was started from rest and had4.80×104 J of kinetic energy when itreached point b, what must be the potential differencebetween a and b?
