There is an electric dipole with dipole moment p above a grounded infinite conducting plane. The dipole is at distance h from the plane and rotated by with respect to the normal vector of the plane. 0 h P 0 Perfect Conductor V = 0 (a) Find the electric force F that exerts on the dipole when 0 = 0 and 7/2. (6 pts) (b) Find the torque as a function of and h. (10 pts) (c) Find the electrostatic potential energy of the system U(h, 8). (5 pts) (d) Let U = |p|/(a). Create a contour plot of U/U in the region h/a [1,3] and 0 [0, ]. (4 pts) (e) After the dipole p is placed initially at a sufficiently high h with the rotation angle 0 = /4, describe its (translational and rotational) motion and explain the reason briefly. You don't need to solve the equation of motion quantitatively. (5 pts) There is an electric dipole with dipole moment p above a grounded infinite conducting plane.
