Question 31
H

The speed of a satellite in a stable circular orbit around the Earth is increased. Which statement about the new stable orbit is correct?

[1]
A

The radius must increase, because a faster satellite needs a larger orbit.

B

The radius must stay the same, because the orbit was already stable.

C

The radius must decrease, because a faster satellite needs a smaller orbit.

D

The radius can take any value, because the speed does not affect it.
