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

  1. AIf both the assertion and reason are true and reason is a correct explanation of the assertion.
  2. BIf both assertion and reason are true but assertion is not a correct explanation of the assertion.
  3. CIf the assertion is true but the reason is false.
  4. 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.
