Question

Two ordinary satellites are revolving round the Earth in same elliptical orbit, then which of the following quantities is conserved

• A. velocity
• B. angular velocity
• C. angular momentum
• D. none of above

Answer 1

Answer: (C)

angular momentum

As in the absence of external torque, $L$ is conserved.

Thus, $L$ should be conserved for the two satellites revolving in same elliptical orbit round the Earth and angular momentum for both must be same.
