The pulleys and strings shown in the figure are smooth and of negligible mass. For the system to remain in equilibrium, the angle `theta` should be

A

`0^(@)`

B

`30^(@)`

C

`45^(@)`

D

`60^(@)`

Text Solution

Verified by Experts

The correct Answer is:
C
From the figure for the equilibrium of the system
`2Tcostheta=sqrt(2)mg` implies `costheta=(1)/(sqrt(2))` implies `theta=45^(@)`
