Question

1. Can centre of gravity of a body be outside the body? If so give an example.
2. Draw the diagram for example in (a) clearly showing centre of gravity.

Answer 1

(a) Yes. The centre of gravity of a body can be outside the body. This happens when the mass is distributed in such a way that the balancing point lies outside the material of the body.

Example: A uniform ring (hoop) has its centre of gravity at the centre of the circle, which is outside the material of the ring.
