Ozone layer lies at a height of about………………….to………………from the surface of earth.

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.

What is the value of 'g' at a height near the surface of earth?

If the value of acceleration due to gravity at a height of 100 km from the surface of earth is g ',then at what depth ,value of acceleration due to gravity wioll again be g'?

Most abundant metal on the surface of earth is:

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.

A satellite is orbiting round the earth at a height h above the surface of the earth. If the distance h is increased, the time period of satellite will

The acceleration on the surface of earth varies
