This is a 3 part question, make sure to show your work:

a) Draw the electric field around a -5.0 x 10-5 C point source charge. Draw the field lines and indicate their direction. Draw two different equipotential lines.

b) Calculate the force between a +8.0 C test point charge and this source charge at a distance of 3.00mm. (C = 1.0x10-6 C)

c) If the test charge were moved further from the source charge, would the change in its potential energy be postive, negative, or zero? Explain your answer.
