In the balance machine shown in the figures. Which arm will move downward after the system is released from rest (assuming stiring, arm of balance machie and the pulley to be light)

A

Left

B

Right

C

remains stationary

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A

Where `T=(2m_(1)m_(2))/(m_(1)+m_(2))g`
Here `tau=T_(1)l-T_(2)l`

and `becauseT_(1)gtT_(2)`
`T_(1)=(2xx2xx3)/(2+3)xx10=24N`
`T_(2)=(2xx4xx1)/(4+1)xx10=16N`
