The ratio of the radius of the earth to that of the motion is 10. the ratio of the acceleration due to gravity on the earth to that on the moon is 6. The ratio of the escape velocity from the earth's surface to that from the moon is

A body of mass 10 kg is taken from equator to pole of the Earth. Calculate the change in its weight, if the radius of the Earth is 6.38 xx 10^(6) m , time period of Earth's rotation about its polar axis is 24 hours.

Find the gravitational potential energy of a body of mass 10 kg when it is at a height of 6400 km from the earth's surface. [Given : mass of the earth and radius of the earth.]

The radius of earth is about 6400Km and that of mars is about 3200 km The mass of the earth is about 10 times the mass of mars An object weight 200N on earth 's surface , then its weight on the surface of mars will be

Calculate the ratio of the angular momentum of the earth about its axis due to its spinning motion to that about the sun due to its orbital motion. Radius of the earth =6400 km and radius of the orbit of the earth about the sun =1.5xx10^8km.

A particle falls on earth : (i) from infinity. (ii) from a height 10 times the radius of earth. The ratio of the velocities gained on reaching at the earth's surface is :

" The escape velocity (in km/s) of a planet whose acceleration due to gravity is "10" times that on the earth and radius "5" times that of the earth "
