If applied torque on a system is zero, i.e., $ \tau =0 $ , then for that system:
Updated On: Aug 15, 2022
- $ \omega =0 $
- $ \alpha =0 $
- $ J=0 $
- $ F=0 $
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
$\tau=I \alpha$ (where$ \tau=$ torque )
$I=$ moment of inertia
$\alpha=$ angular acceleration
if $ \tau=0 $
$ I \alpha=0 $
But $ I \neq 0 $
$\therefore \alpha=0$

Concepts Used:
System of Particles and Rotational Motion
- The system of particles refers to the extended body which is considered a rigid body most of the time for simple or easy understanding. A rigid body is a body with a perfectly definite and unchangeable shape.
- The distance between the pair of particles in such a body does not replace or alter. Rotational motion can be described as the motion of a rigid body originates in such a manner that all of its particles move in a circle about an axis with a common angular velocity.
- The few common examples of rotational motion are the motion of the blade of a windmill and periodic motion.
