Question

1. The work done by an external force to move a -7.00 uC charge from point A to point B is 1.70x10^-3J. If the charge was started from rest and had 4.80x10^-4J of kinetic energy when it reached point B, what must be the potential difference between A and B?

2. A dialectic is pulled out from between the plates of a capacitor which remains connected to a battery. What changes occur to (A)the capacitance,(b) the charge on the plates, (c) the potential difference, (d) the energy stored in the capacitor, and, (e)the electric field? Explain your answers.
