An electric dipole with atomic charges +q and -q are fixed to the ends of a rigid neutral molecule with length C. The mass of the charges are Nm and the mass of the rigid rod-like mnolecule is M, note that N is the number of nucleons in each of the two charged atoms. The electric dipole is set oscillating in a uniform electric field, E. The net torque exerted on the dipole is 7 = 7xE. Find the simple harmonic oscillation equation for the orientation of the dipole, the solution to the D.E., and the angular frequency in terms of the given information. Be sure to include all undetermined coefficients. -4 +4 > axis of oscillation diagram of dipole during oscillition +4 axis of oscillation < dipole moment of ebctic dipede e - P = 9 %3D Yerque acting an dipal = = P XÈ
