A molecule consists of an electric dipole with charges q and -q equal to 1x10^-9 C separated by a distance of 0.5 nm. Assume that the masses of the two sides of the dipole are both equal to 1x10^-20 kg. The dipole is placed in a uniform electric field of magnitude 20,000 N/C. a. The dipole is rotated from an angle of 0º to an angle of 45º with respect to the electric field by an external agent. Calculate the work done against the electric field. b. Calculate the rotational inertia of the dipole about an axis passing through the center of mass. c. The dipole is set into a small angle oscillation. Calculate the period of the oscillation.
