If $r$ denotes the distance between the sun and the earth,then the angular momentum of the earth around the sun is proportional to

$A$ satellite is to revolve around the Earth in a circle of radius $8000\, km$. The speed at which this satellite must be projected into an orbit will be......... $km/s$.

$A$ satellite can be in a geostationary orbit around a planet at a distance $r$ from the centre of the planet. If the angular velocity of the planet about its axis doubles,a satellite can now be in a geostationary orbit around the planet if its distance from the centre of the planet is

Orbital velocity of an artificial satellite does not depend upon

Choose the correct statement from the following: The radius of the orbit of a geostationary satellite depends upon

The centripetal force acting on a satellite orbiting around the Earth and the gravitational force of the Earth acting on the satellite are both equal to $F$. The net force on the satellite is
