The distance of geostationary satellite from the centre of the earth (radius R) is nearest to

A satellite of Earth is going around in an elliptical orbit. The smallest distance of the satellite from the centre of the earth happens to be 2R (where R = radius of the earth). ind the upper limit of the maximum speed of such a satellite.

Two satellites are at distances of 2R and 4R respectively from the surface of earth. The ratio of their time periods will be :

Two identical satellites A and B are circulating round the earth at the height of R and 2 R respectively, (where R is radius of the earth). The ratio of kinetic energy of A to that of B is

The gravitational potential energy of a body at a distance r from the centre of the Earth is U where r gt R (radius of Earth). What is the weight of body at the point ?
