Mass of a body is 20 kg at the surface of earth. AT what depth does its mass reduce to 5 kg?

Mass of an object is 10 kg. What is its weight?

As you have learnt in the text, a geostationary satellite orbits the earth at a height of nearly 36,000 km from the surface of the earth. What is the potential due to earth’s gravity at the site of this satellite ? (Take the potential energy at infinity to be zero). Mass of the earth = 6.0Xx10^24 kg , radius = 6400 km.

Mass of an object is 7 kg. What is its weight?

The centre of mass of an extended body on the surface of the earth and its centre of gravity

Calculate the weight of an astronaut whose mass is 80 kg on the surface of earth and on the surface of moon. Given that the acceleration due to gravity at moon is one-sixth of that of earth.

Mass of an object is 10 kg. What is the weight on the earth (g = 9.8 ms^-2) ?

If mass of a body is M on the earth surface, then the mass of the same body on the moon surface is

What is the mass of a bdy of 5 kg at the centre of earth?

A body of mass 6 kg is kept at a height of 5 m from the surface of earth. Find the potential energy of the body.
