A massless string passes over a friction...

A massless string passes over a frictionless pulley and carries two masses `m_1` and `m_2(m_1 > m_2)` at it's ends. If `g` is the acceleration due to gravity, then the thrust on the pulley is `(m_1>m_2)`.

A

`frac{2m_1m_2}{m_1-m_2}`

B

`frac{2m_1m_2}{m_1+m_2}`

C

`frac{4m_1m_2}{m_1+m_2}`

D

None of these
