A dipole consists of charges +e and -e separated by 0.61 nm. It is in an electric field E = 2.9 × 104 N/C.
(a) What is the value of the dipole moment?
(b) What is the torque on the dipole when it is perpendicular to the field?
(c) What is the torque on the dipole when it is at an angle of 45° to the field?
(d) What is the work required to rotate the dipole from being oriented parallel to the field to being antiparallel to the field?
