Question

Which of the following is/are true about the centre of gravity?

• A. It is the point at which the mass of a body is assumed to be concentrated.
• B. A body can have multiple centres of gravity.
• C. The centre of gravity of an object need not always coincide with its geometric centre.
• D. A body can be balanced at its geometrical centre if it coincides with the centre of gravity

Answer 1

Answer: (A), (C), (D)

The correct options are
A

It is the point at which the mass of a body is assumed to be concentrated.

C

The centre of gravity of an object need not always coincide with its geometric centre.

D

A body can be balanced at its geometrical centre if it coincides with the centre of gravity

It is the point at which the mass of a body is assumed to be concentrated. It is unique for every body. For objects having uniform density, centre of gravity coincides with the geometric centre. A body can be balanced at its geometrical centre if it coincides with the centre of gravity
