CBSE Class 9 Physics Gravitation
- what is the weight of an object at the centre of the earth
- what is Newton's contribution on gravitation?
- two satellites of a planet have period 32 day and 256 days if the radius of orbit of former is R, find the orbital radius of the letter
- weight of the body is zero in free fall why?
- my doubt is the value of G is 60673multiply10-11power but why we use some no in some different numericals like use of 6.6, some times 6.7 why please ans this ques now 🙏
- Find the force of gravitational attraction between the earth (m = 6 x 1024 kg) and 80 kg man if he is standing at sea level. The distance of man from earth's center is 6.38 x 106 m.
- a stone is released from the top of the tower of height 19.6 m calculate its final velocity just before touching the ground
- what is gravitation
- how does the force of gravitation between two objects change when the distance between them is reduced to half
- The gravitation force between two bodies varies with distance r as
