A dipole moment of 0.50 (e)(nm) is placed in a uniform electric field that has a agnitude of 4.0x104 N/C. What is the magnitude of the torque on the dipole when (a) the dipole is aligned with the electric field, b) the dipole is perpendicular to the electric field and c) the direction of the dipole makes and angle of 30 degrees with the direction of the electric field?
Defining the potential energy to be zero when the dipole is transverse to the electric field, find the potential energy of the dipole for orientations listed in (a) and (c)
