A point charge of 3.0 nC is moved from x=1.0m to x=1.5m in an electric field of 5.0 N/C with the same direction as the motion of the charge. a. How much work is done on the charge by the electric force? b.) What is the change in potential energy of the charge?0 Compute the electric potential from a source char e of +5 11:10'13 C if a test charge will be placed 2.08x10'3 m from it. How does electric potential relate with work, PE and electric field
