Answer 2

CM lies nearer to heavier body.

• The centre of mass lies between the two particles of the system and is closer to the heavier body.
• The centre of mass is that point of the system where the mass of the body can be concentrated and from the gravitational force of the system can be concentrated.
• The centre of mass cannot lie outside the body, however there are some unusual cases also, fo example in a ring, the centre of mass lies at the centre where there is no mass.
