For the moon to cease as the earth's satellite, its orbital velocity has to be increased by a factor of:
1. | \(2\) | 2. | \(\sqrt{2}\) |
3. | \(1/\sqrt{2}\) | 4. | \(4\) |
How many times is escape velocity, of orbital velocity for a satellite revolving near earth?
(a) times (b) 2 times
(c) 3 times (d) 4 times
The value of escape velocity on a certain planet is 2 km/s. Then the value of orbital speed
for a satellite orbiting close to its surface is:
1. 12km/s
2. 1km/s

An earth satellite of mass m revolves in a circular orbit at a height h from the surface of
the earth. R is the radius of the earth and g is acceleration due to gravity at the surface
of the earth. The velocity of the satellite in the orbit is given by:
1.
