Solution refer to the attachment.

Thanks..

Answer 2

Answer:

Orbit speed of the satellite around the earth is

where,

G = Universal gravitational constant

M = Mass of earth

r = Radius of the orbit of the satellite

For satellite A

...(i)

For satellite B

...(ii)

Dividing equation (ii) by equation (i), we get

or

Substituting the given values, we get

or
