Question

A satellite revolving around very close to the earth, has speed vo, nearly

Answer 1

Answer:

We know that for a satellite moving in orbit Gravitational force = Centripetal force

So,

r

2

GM

=

r

mv

2

Hence r is the radius of the earth as satellite is very close to it.

So, by rearranging

v

2

=

r

GM

v=

r

GM

g=

r

2

GM

v=

gr
