Question

Derive an expression for centre of mass of two particle system if origin is at one of the mass of particle and origin is at centre of mass

Answer 1

Explanation:

This is nothing but the position vector and is called the centre of the mass of the two-particle system. It is the point where the total external force is supposed to act. For a two-particle system, the centre of mass lies between the two particles and on the line joining them.The center of mass is the point where all of the mass of the object is concentrated.The position of the centre of mass of a rigid body depends upon the shape and distribution of mass in the body.In the given system it is much closer to the heavier particle than to the other.
