A satellite in circular orbit has speed v and period T at radius r. Another satellite at radius 4r has
A.speed v/2 and period 8T
B.speed v/4 and period 8T
C.speed v/2 and period 4T
D.speed 2v and period 8T
Explanation
Core Concept
v ∝ r^(-1/2) so v/2; T ∝ r^(3/2) so 8T.
Correct Answer
Aspeed v/2 and period 8T
