Three masses in contact is as shown above. If force F is applied to mass `m_1` , then the contact force acting on mass `m_2` is

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

`(m_1F)/(m_1 + m_2 + m_3)`

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

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

Text Solution

Verified by Experts

The correct Answer is:

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