NEET2002PhysicsOscillationsActual
Assertion : The time-period of pendulum, on a satellite orbiting the earth is infinity. Reason : Time-period of a pendulum is inversely proportional to g .
Options
- AIf both the assertion and reason are true and reason is a correct explanation of the assertion.
- BIf both assertion and reason are true but assertion is not a correct explanation of the assertion.
- CIf the assertion is true but the reason is false.
- DIf both assertion and reason are false.
Correct answer
A. If both the assertion and reason are true and reason is a correct explanation of the assertion.
Step-by-step solution
Time-period of simple pendulum, T=2 l g Thus time-period is inversely proportional to g (where g is acceleration due to gravity). And as the value of g on a satellite is zero, therefore time-period of pendulum is infinity.
