An electric dipole consists of charges +e and -e separated by 0.76 nm. It is in an electric field of strength 2.50 10^4 N/C.
A) What is the value of the dipole moment? (in C x m)
B) What is the torque on the dipole when it is perpendicular to the field? (in m x N)
C) What is the torque on the dipole when it is at an angle of 45 degrees to the field? (in m x N)
D) What is the work required to rotate the dipole from being oriented parallel to the field to being antiparallel to the field?
