STANDARD Physics Pendulum Motion Assertion Reason Question
Type: Assertion Reason-conceptual-Medium-Class 11
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.
A
Both assertion and reason are true and reason is the correct explanation of assertion.
B
Both assertion and reason are true but reason is not the correct explanation of assertion.
C
Assertion is true but reason is false.
D
Both assertion and reason are false.
Correct Answer
Option B
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.
