Consider a closed system of three charged particles with charges 3 e, e and 7 e respectively, where e is the electronic charge. Their corresponding masses are 6 ~m , 2 ~m and 14 m where m is the mass of electron. The particles maybe moving in an arbitrary

Options

1. Athe cyclotron frequencies of all the particles are same.
2. Bthe dipole moment of the system is independent of the choice of the origin of coordinates.
3. Cthe magnetic moment of the system is proportional to the total angular momentum.
4. Dthe second time derivative of the dipole moment vector is zero for all times.
