A mass M is suspended as shown in fig. The system is in equilibrium. Assume pulleys to be massless. K is the force constant of the spring.

If each of the pullies A and B has mass M, then find the net tension force acting on the lower support. Asumme pulleys to be frictionaless.

A

`2Mg`

B

`6Mg`

C

`3Mg`

D

`4Mg`

Text Solution

Verified by Experts

The correct Answer is:
D
`T_(1)=3Mg`
Net tension at lower support
`T+T_(1)=Mg +3Mg=4Mg`.
