AIPMT PRELIMS 2005 Physics Simple Harmonic Motion MCQ Question

Type: MCQ-numerical-Medium-Class 11

A particle executing simple harmonic motion of amplitude 5 cm has maximum speed of 31.4 cm/s. The frequency of its oscillation is:

A

2 Hz

B

1.5 Hz

C

0.5 Hz

D

1 Hz

Correct Answer

Option D

Detailed Explanation

The maximum speed in simple harmonic motion is given by v_max = ωA, where ω is the angular frequency and A is the amplitude. Given v_max = 31.4 cm/s and A = 5 cm, ω = v_max/A = 31.4/5 = 6.28 rad/s. The frequency f is ω/2π = 6.28/2π = 1 Hz.
