Assertion: The time period of revolution...

Assertion: The time period of revolution of a satellite close to surface of earth is smaller then that revolving away from surface of earth.
Reason: The square of time period of revolution of a satellite is directely proportioanl to cube of its orbital radius.

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:
A
According to Kepler.s law `T^2propr^3prop(R+h)^3`
i.e. if distance of satellite is more then its time period will be more.
