Problem
A point charge +5μC is fixed in space. Another point charge +1μC is moved along the line joining them from a distance of 10cm to 20cm, slowly and without acceleration.
(i) Determine the change in electrostatic potential energy of the system.
(ii) State the work done by an external agent during this process and its sign.
