Assertion: The speed of revolution of an artificial satellite revoving very near the earth is `8kms^(-1)`.
Reason: Orbital velocity of a satellite, becomes independent of height near earth.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If the assertion and reason both are false

Text Solution

Verified by Experts

The correct Answer is:
