STANDARD Physics Pendulum Motion Assertion Reason Question
Assertion : If a pendulum is suspended in a lift and lift is falling freely, then its time period becomes infinite. Reason : Free falling body has acceleration equal to acceleration due to gravity.
Both assertion and reason are true and reason is the correct explanation of assertion.
Both assertion and reason are true but reason is not the correct explanation of assertion.
Assertion is true but reason is false.
Both assertion and reason are false.
Correct Answer
Detailed Explanation
In free fall, the acceleration of the pendulum is equal to the acceleration due to gravity, making the effective acceleration zero. Thus, the time period becomes infinite.
