Question 30
H

Satellites X and Y are in stable circular orbits around the Earth. The orbit of X has a smaller radius than the orbit of Y. Which statement is correct?

[1]
A

X travels more slowly than Y, because X is closer to the Earth.

B

X travels faster than Y, because X is in an orbit of smaller radius.

C

X and Y travel at the same speed, because both orbits are stable.

D

X travels faster than Y, because gravity acts on X but not on Y.
