Problem 5: A simple dipole consists of two charges with the same magnitude, q,
but opposite sign separated by a distance d. The EDM (electric dipole moment) of E
the configuration is represented by p which has a magnitude p = qd and a
direction pointing from the negative charge towards the positive charge. If the
dipole is located in a region with an electric field, E, then it experiences a torque
T= p x E. In this problem we will explore the rotational potential energy of an
electric dipole in an electric field.

notation.
