Question

A satellite is orbits around a planet its velocity is v is found todepend on radi of orbit ,mass of planet and universal gravitation constant find the expression for v of physical quantity

Answer 1

The necessary centripetal force for the circular motion of the satellite in an orbit is provided by the gravitational force of attraction between the satellite and the planet.
Let's assume,
m: mass of the satellite
M: mass of the planet
G: Universal Gravitational Constant
R: radius of the circular orbit
v: velocity of the satellite

The following image will provide the derivation for the velocity of the satellite revolving in a circular orbit:
