Question: The work done by an external force to move a 8.5C charge from point a to point b is 15.0 X 10-4J. If the charge

The work done by an external force to move a –8.5μC charge from point a to point b is 15.0 X 10-4J. If the charge was started from rest and had 4.82 X 10-4J of kinetic energy when it reached point b what must be the potential difference between and b?
