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.

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 :

Suppose there existed a planet that went around the sun twiche as fact as the earth. What would by its orbital size?

In Rutherford's nuclear model of the atom, the nucleus (radius about 10^(-15)m ) is analogous to the sum about which the electron moves in orbit (radius about 10^(-10)m ) like the earth orbits around the sun. If the dimensions of the solar system had the same proportions as those of the atom, would the earth be closer to or further away form the sun than actually it is ? The radius of earth's orbit is about is 1.5xx10^(11)m . The radius of the sun is taken as 7xx10^8m .

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.

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 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
