a. Two point charges each of magnitude +5.010-9 C are placed 8.0 cm apart in air. Calculate, i. the electric potential, and ii. the electric field strength at a point, P which is 5.0 cm away from each charge. b. An electron of charge 1.610-19 C moves from a point midway between the charges and on the line joining them, to point P. i. Calculate the work done. ii. Discuss the energy changes in the process
