A diatomic molecule is made of two masses and which are separated by a distance . If we calculate its rotational energy by applying Bohr's rule of angular momentum quantisation, its energy will be given by ( is an integer)

Answer: (D)

Solution

The moment of inertia about the centre of mass is and Bohr's rule gives (written in the options), so $E =
