A uniform rod of mass `15 kg` is held stationary at 37 degree with the help of a light string as shown in Fig. The tension in the string is

A

`150N`

B

`225N`

C

`100N`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
C
The free body diagrm of the rod is shown in the figure (Force exerted by the hinge on the rod are not shown).
ltbr.gt Take torque about the hinge,
`Txx3-15gxx2=0`
`implies T=100N`
