A satellite A of mass m is at a distance of r from the centre of the earth. Another satellite B of mass 2m is at distance of 2r from the earth's centre. Their time periode are in the ratio of
Imagine a new planet having the same density as that of earth but 3 times bigger than the earth in size. If the acceleration due to gravity on the surface of earth is g and that on the new plane is g , then :
Suppose there existed a planet that went around the sun twice as fast as the earth.What would be its orbital size as compared to that of the earth ?
Buoyant Force is the upward force that acts in the direction opposite to that of weight.Type 1 for true and 0 for false
Magnitude of buoyant force depends on __________.
What is the magnitude of the gravitational force between the earth and a 1 kg object on its surface? (Mass of the earth is 6×1024 kg and radius of the earth is 6.4×106 m.)
A satellite S is moving in an elliptical orbit around the earth. The mass of the satellite is very small compared to the mass of the earth.
How will you 'weigh the sun', that is estimate its mass? The mean orbital radius of the earth around the sun is 1.5× 108 km.
