A diatomic molecule is made of two masses `m_(1) and m_(2)` which are separated by a distance r. If we calculate its rotational energy by applying Bohr's rule of angular momentum quantization, its energy will be given by (n is an integer)

Options

A. `((m_1+m_2)^2n^2h^2)/(2m_1^2m_2^2r^2)`
B. `(n^2h^2)/(2(m_1+m_2)r^2)`
C. `(2n^2h^2)/((m_1+m_2)r^2)`
D. `((m_1+m_2)n^2h^2)/(2m_1m_2r^2)`
