The reduced mass of two particles having masses $m$ and $2\, m$ is
Updated On: Jun 18, 2022
- $2\,m$
- $3\,m$
- $\frac{2m}{3}$
- $\frac{m}{2}$
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Reduced mass $= \frac{m \times 2m}{m +2m}$
$ = \frac{2m}{3}$
$ = \frac{2m}{3}$

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.
