4. A negative charge, -Q (Q is a magnitude in Coulombs) of mass m, is released from rest in the presence of an electric field. The charge experiences a force and begins to move. a) As the charge moves, does the potential energy of the system (this includes the source of the electric field which remains fixed in space) increase, decrease or stay the same? b) The charge moves through a potential difference, AV after being released from rest. Is the value of AV positive, negative or zero? c) What is the speed of the charge after it has moved through AV, starting from rest? (Note that work done by gravity can be neglected here.)
