A satellite orbits around the earth in a circular orbit with a speed `upsilon` and orbital radius `r`. If it loses some energy, then `upsilon` and `r` changes as

Options

A. `d` will increases, `v` will increases
B. `d` will increases, `v` will decreases
C. `d` will decreases, `v` will decreases
D. `d` will decreases, `v` will increases

Answer

D

Explanation

`(mv^(2))/d=(GMm)/(d^(2)) implies v=sqrt((GM)/d) implies v prop1/(sqrt(d))`
