NEET Physics Time Period & Frequency Assertion Reason Question
Assertion (A): The time period of a simple pendulum on the moon is longer than its time period on Earth.
Reason (R): The acceleration due to gravity on the moon is less than that on Earth.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true, but R is false.
A is false.
Correct Answer
Detailed Explanation
The time period of a pendulum T is given by T = 2π√(l/g). Since g on the moon is less than g on Earth, the time period on the moon is longer. This is directly explained by the reason provided.
