Two satellites a and b of the same mass are orbiting earth in concentric orbits. the distance of satellite b from earth’s center is twice that of satellite a. what is the ratio of the tangential speed of b to that of a?

ratio of tangential velocity of satellite b and a will be 0.707

Explanation:

We have given distance of satellite B from satellite A is twice

So

Tangential speed of the satellite is given by

, G is gravitational constant. M is mass of satellite and r is distance from the earth

We have to find the ratio of tangential velocities of b and a

From the relation we can see that tangential velocity is inversely proportional to square root of distance from earth

So

So ratio of tangential velocity of satellite b and a will be 0.707

the ima (higher than 1m) will be greater than the ima with the height of 1m.
