Three blocks m1,m2 and m3 are arranged ...

Three blocks `m_1,m_2 and m_3` are arranged as shown. Find the force (F) that must be applied on `m_3` so that the blocks `m_1 and m_2` are relatively at rest w.r.t. `m_3`

A

`F=((m_3+m_2+m_3)m_1g)/(m_2)`

B

`F=((m_1+m_2+m_3)m_2g)/(m_1)`

C

`F=((m_1+m_2-m_3)m_2g)/(m_1)`

D

`F=((m_1+m_2-m_3)m_1g)/(m_2)`
