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 an oscillator is inversely proportional to the square root of the spring constant. | Reason (R): A stiff spring corresponds to a large angular frequency and a small time period.

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

According to the formula T = 2π√(m/k), the time period T is inversely proportional to √k. A stiff spring (high k) indeed results in a smaller time period, as stated in the reason.
