we find that it moves away fromqfixedand gains kinetic energy which is exactly equal to the energy we used to moveqtesttowardqfixed. We say that the energy we used to moveqtestwas stored aspotential energy,U. We define the potential at any place A in space as being the work done to...

The electric potential energy is a form of potential possed by a charged object by the virtue of its position in an electric field. In order to move a charged object from one point to another in an electric field without changing its kinetic energy, work must be done on the ob...

Point A is at an electric potential of +75V and point B is at an electric potential at -75V. The work done by an external force to move a charge from A to B is 7.5 x 10-4J. If the charge starts from rest at A and has kinetic energy of 2.4 x 10-4J when it reaches B, wh...
