Find `m_(3)` if the system is in equilibrium the incline is smooth and string and pulley are light

A

`m_(1)sin theta`

B

`m_(1)-m_(2)`

C

`m_(1)sin theta -m_(2)`

D

`m_(1) cos theta - m_(2)`

Text Solution

Verified by Experts

The correct Answer is:
c
`rarrm_(1) g sin theta =T rarr T=m_(2)g +T_(1) rarr T_(1)=m_(3)g rarr m_(3)=m_(1) sin theta -m_(2)`
