Answer:1: If the height of the orbit of a satellite from the earth surface is increased, the tangential velocity of the satellite will decrease.
< br>
Explaination :: The Gravitational force (F) exerted by the earth on the satellite will decrease if the height of the orbit of the satellite from the earth’s surface is increased. Hence the tangential velocity of the satellite will decrease.
Answer 2 : The initial velocity (during launching) of the Managalyaan, must be greater than escape velocity of the earth.
Explanation : Velocity of a satellite must be more than the escape velocity of the earth if a satellite is to travel beyond the gravitational pull of the earth
