Question

A satellite orbiting Earth at an orbital radius r has a velocity v. Which represents the velocity

if the satellite is moved to an orbital radius of 5r? (1 point)
​

Answer 1

v / √5

Step-by-step explanation:

Centripetal acceleration = acceleration due to gravity

v² / r = GM / r²

v² = GM / r

If the radius is increased to 5r:

u² = GM / (5r)

u² = v² / 5

u = v / √5
