Statements:
a) Position of C.m depends on acceleration due to gravity where as position of C.g independent on acceleration due to gravity.
b) Centre of gravity of a body is defined to know the amount of stability of the body and the center of mass of the body is defined to describe the nature of motion of the body.

View answer and explanation

Correct option: B

a is false, b is true

Option B is correct because the position of the center of mass is independent of gravity, while the center of gravity depends on gravity. The second statement correctly describes the purpose of each concept.
