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

A

250 N

B

255 N

C

100 N

D

None of the above

Text Solution

Verified by Experts

The correct Answer is:
C

The free body diagram of the rod is shown in figure. (Force exerted by hinge on rod are not shown. Take torque about hinge

`T xx 3 -15g xx 2=0 rArr T = 100 N`
