Choose the wrong statements about the centre of mass (CM) of a system of two particles
The CM lies on the line joining the two particles midway between them
The CM lies on the line joining them at a point whose distance from each particle is proportional to the square of the mass of that particle
The CM is on the line joining them at a point whose distance from each particle is proportional to the mass of that particl
The CM lies on the line joining them at a point whose distance from each particle is inversely proportional to the mass of that particle
