A metal rod of uniform thickness and of ...

A metal rod of uniform thickness and of length `1m` is suspended at its `25cm` division with help of a string. The rod remains horizontally straight when a block of mass `2kg` is suspended to the rod at its `10cm` division. The mass of rod is

A

`0.4`kg

B

`0.8` kg

C

`1.2`kg

D

`1.6`kg

Text Solution

Verified by Experts

The correct Answer is:
C

clockwise torque = anti clockwise torque ` mg xx 25 = 2g xx15`
