What is the difference between centre of mass and centre of gravity?

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

Find the distance between centre of gravity and centre of mass of a two particle system attached to the ends of a light rod. Each particle has same mass. Length of the rod is R, where R is the radius of earth.

Statement-1 : The centre of mass and centre of gravity of a body are two different positions in general. and Statement-2 : The centre of mass and centre of gravity of a body coincide if graviational field is unifrom.

The distance between the point of suspension and the centre of gravity of a compound pendulum is l and the radius of gyration about the horizontal axis through the centre of gravity is k , then its time period will be

A uniform circular disc of mass M and radius R is pivoted at distance x above the centre of mass of the disc, such that the time period of the disc in the vertical plane is infinite. What is the distance between the pivoted point and centre of mass of the disc ?

The centre of mass of a body

What is the distance of centre of mass of a half fring from centre if the ring has radius =0.5 m [XI]

Is centre of mass always a reality ?

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

A : If an object is taken to the centre of earth, then its centre of gravity cannot be defined. R : At the centre of earth acceleration due to gravity is zero.
