Geostationary And Polar Satellites MCQ - Practice Questions with Answers

The mean radius of the earth is R, its angular speed about its own axis $\omega$ and the acceleration due to gravity at the earth's surface is $g$. The cube of the radius of orbit of a 'geostationary satellite' will be:

A geostationary satellite orbits around the earth in a circular orbit with a radius of 36000 km. Then the time period of a spy satellite orbiting a few hundred kilometres above the earth's surface ($\mathrm{R}_{\text {earth }}=6400 \mathrm{~km}$ ) will approximately be

What should be the period of rotation of the earth so as to make any object on the equator weight half of its present value?

A satellite that is geostationary in a particular orbit is taken to another orbit, the distance of which is twice that of the earlier orbit. The time period of the satellite in the second orbit is
 

The mean radius of the earth is R, its angular speed about its own axis and the acceleration due to gravity at the earth surface is g. The cube of radius of orbit of ‘geostationary satellite’ will be:
