Orbit of Artificial Satellites
Find vevo where
ve: Escape velocity of satellite at the surface of earth.
vo: Orbital velocity of satellite orbiting at the surface of earth.
A particle on the Earth's surface is given a velocity equal to its escape velocity. Its total mechanical energy remains
The ratio of the K.E. required to be given to the satellite to escape earth's gravitational field to the K.E. required to be given so that the satellite moves in a circular orbit just above earth atmosphere is
Two earth-satellites are revolving in the same circular orbit around the center of Earth. They must have the same

Is balanced by the gravitational pull of moon
Is balanced by the gravitational pull os sun
Makes it weightless
A satellite X is launched into a circular orbit of radius R around the earth while a second satellite Y is launched into an orbit of radius 4R. The ratio of the time periods of Y to X is ______.
If ve and vo represent the escape velocity and orbital velocity of a satellite corresponding to a circular orbit of radius R, then
