Three blocks A,B, and C are suspended as shown in fig. Mass of each of blocks A and B is m. If the system is in equilibrium, and mass of C is M then

A

`Mgt2m`

B

`M=2m`

C

`Mlt2m`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
C
At equation `2T cos theta=Mg, T=mg`
`cos theta =(Mg)/(2mg) =(M)/(2m)`
`implies cos theta lt 1`
`(M)/(2m) lt1 implies Mlt 2m`
