Question

Figure 1.0a shows an electric dipole in a uniformelectricfield with magnitude 5.0 × 105

N/C directed parallel to the plane of the figure. Thechargesare ± 1.6 × 10-19C; both lie in

the plane and are separated by 0.125nm.

Find

a) The net force exerted by the field on the dipole;

b) The magnitude and direction of the electricdipolemoment;

c) The magnitude and direction of the Torque;

d) The potential energy of the system in position shown.
