Physics-Time Period & Frequency

NEET Physics Time Period & Frequency Assertion Reason Question

Type: Assertion Reason-assertion-Medium-Class 11

Assertion (A): The time period of a simple pendulum is independent of its mass. | Reason (R): The time period of a simple pendulum depends on the length of the pendulum and the acceleration due to gravity.

A

Both A and R are true, and R is the correct explanation of A.

B

Both A and R are true, but R is not the correct explanation of A.

C

A is true but R is false.

D

A is false.

Correct Answer

Option A

Detailed Explanation

The time period of a simple pendulum is given by the formula T = 2π√(L/g), which indicates that the mass of the pendulum does not affect the time period. The explanation correctly states that the time period depends on the length and gravity.
