Centre of mass of a body is a point where its whole ______ acts whereasits centre of gravity is a point where its whole ________ acts

Centre of mass is point

The centre of mass of an extended body on the surface of the earth and its centre of gravity

Can centre of mass of a body lie where there is absolutely no mass ?

Statement-1: The centre of mass of body may lie where there is no mass. Statement-2: Centre of mass of a body is a point, where the whole mass of the body is supposed to be concentrated.

Can the centre of mass of a body be at a point outside the body?

Statement-1 : The centre of mass of a body may lie where there is no mass. Statement-2 : The centre of mass has nothing to do with the mass.

For any given body, the centre of the mass of a body always coincides with its centre of gravity.

Assertion: Centre of mass of a rigid body always liees inside the body. Reason: Centre of mass and centre of gravity coincide if gravity is uniform.

Does centre of mass and centre of gravity body always coincide?

(1) Centre of gravity (C.G.) of a body is the point at which the weight of the body acts, (2) Centre of mass coincides with the centre of gravity if the earth is assumed to have infinitely large radius, (3) To evaluate the gravitational field intensity due to any body at an external point, the entire mass of the body can be cosidered to be concentrated at its C.G.., (4) The radius of gyration of any body rotating about ab axis is the length of the perpendicular dropped from thr C.G. the body to the axis. which one of the following paries of statements is correct ?
