Two masses m(1) and m(2) are suspended ...

Two masses `m_(1) and m_(2)` are suspended together by a massless spring of constant k. When the masses are in equilibrium, `m_(1)` is removed without disturbing the system. Then the angular frequency of oscillation of `m_(2)` is

A

`sqrt (k/m_1), `(m_2g)`/k

B

`sqrt (k/m_1), `(m_1g)`/k

C

`sqrt (k/m_2), `(m_1g)`/k

D
