A body weighs 63 N on the surface of the earth. What is the gravitational force on it due to the earth at a height equal to half the radius of the earth?

What is the mass of the earth?

What is the length of the radius of the earth?

What do we call the gravitational force between the earth and an object?

If the change in the value of ‘g’ at a height h above the surface of the earth is the same as at a depth x below it, then (both x and h being much smaller than the radius of the earth):

What is the gravitational force on a body inside a spherical shell? Why is it so?

Write the formula to find the magnitude of the gravitational force between the earth and an object on the surface of the earth.

If g is the acceleration due to gravity on the earth’s surface, the gain in the potential energy of an QBject of mass m raised from the surface of the earth to a height equal to the radius R of the earth is :

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 = 6.0 xx 10^24 kg, radius = 6400 km

Gravitational force on the surface of the moon is only 1/6 as strong as gravitational force on the earth. What is the weight in newtons of a 10 kg object on the moon and on the earth?
