To know about the centre of gravity of the atmosphere of the earth Ravi ask some questions to his teacher guess which questions he asked and the answer given by the teacher
Answers
Ravi can ask some questions like
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.
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.
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.
Answer:
From the question'
The key points are center of gravity
So, he can frame question like,
1)What is center of gravity
Answer: The center of gravity definition can be given as the average location of the weight of the object.
2)What is the difference between center of mass and center of gravity
the difference is center of mass does not depend on gravitational field.
And at last to know about the center of gravity of the atmosphere of the earth
Assume earth is spherical then surrounding of field also spherical,so geometrical center will be the same as location of center of gravity.
But,in reality earth is not spherical,so location of the center of gravity will be nearer to its geometrical center.
Hope it helps
