P#10
A man weighs 440N on the earth. What will be his weight one earth radius above its surface.

P#11
A geostationary satellite is revolving in a circular orbit at a height of 36000 km from the surface of the earth. What will be the value of 'g' on the satellite?

P#12
The earth's radius is about 6.4 x 10^6m. An object that has a mass of 20kg is taken to a height of 1.6 x 10^6 m above the earth's surface. (1) What is the mass of the object at this height? (ii) How much does the object weigh at this height?
