Problem
A uniform electric field is set with two parallel plates 4 cm apart. The top plate is connected to a supply kept at 50 V. The bottom plate is kept at a potential of 10 V.
(1) Suppose a 1 C charge was sitting on the underside surface of the top plate. How much electrical potential energy would it have?
(2) Suppose the 1 C charge sat on the upper side of the bottom plate. How much electrical potential energy would it have?
(3) How much work would have to be done to move the 1 C charge from the bottom plate to the top plate?
(4) In answering part c above, was it necessary to consider the *actual* path along which the 1 C charge would move?
