Question

Where should the centre of gravity of a body be?

• A. It must lie within the body
• B. It may be near but not essentially within the body
• C. It changes its position from time to time
• D. It must be outside the body

Answer 1

The correct option is B It may be near but not essentially within the body

The centre of gravity of the body lies at the point where the resultant weight of the body is supposed to act. Centre of gravity may or may not lie inside the body. For example, the centre of gravity of the rim lies at its geometric centre.

* The CG of an object may be located where no actual material exists.
