The following questions refer to the configuration involving an electric dipole and an external charged particle depicted below: 3. Suppose that the electric dipole has a length of 5 mm and the positive end has charge 8 nC. Let's say that the external particle is 2 cm from both ends of the dipole, carrying a charge of -2 µC. What is the net electric force acting on the dipole? [A positive net force points up, a negative one points down.] What is the net torque on the dipole relative to its center point? [Positive torque implies counterclockwise motion, negative implies clockwise.]
