Question

The centre of gravity of a body is the point about which the algebraic sum of moments of weights of all the particles constituting the body is ______.

Options

• 1

• >1

• <1

• 0

Answer 1

The centre of gravity of a body is the point about which the algebraic sum of moments of weights of all the particles constituting the body is 0.

Explanation:

The centre of gravity of a body is the point through which its entire weight is considered to act. At this point, the algebraic sum of moments of the weights of all particles of the body is zero. Hence, the body remains balanced about its centre of gravity.
