Ravi can ask some questions like
1.what is centre of gravity ?
ans : centre of gravity is a point at which distribution of weight is equal in all directions or you can say that it is a point where whole mass is concentrated of system.
2.what is the difference between centre of gravity and centre of mass ?
Ans : centre of gravity depends on gravitational field while centre of mass doesn't depend on gravitational field. it is a point at which distribution of mass is equal in all directions.
3. identify the position of centre of gravity of atmosphere of the earth ?
ans : if we assume earth is a uniform spherical body then atmosphere is like a cover of spherical body outside the earth 's surface. so, centre of gravity of earth's atmosphere will be geometrical centre of earth but you know as well, shape of earth is not a perfect spherical so, it centre of gravity doesn't lie geometrical centre but its location near of that.
