In the figure at the free end a force F is applied to keep the suspended mass of 18 kg at rest. The value of F is `:`

A

`60N`

B

`120N`

C

`180N`

D

`240N`

Text Solution

Verified by Experts

The correct Answer is:
D


`3F=180`
`F=60N`
`T=4F=210N`
Force balance on system
`T=F+180`
`T=60+18=240N`.
