STANDARD Physics Simple Harmonic Motion MCQ Question
Type: MCQ-conceptual-Medium-Class 11
The displacement of a particle is represented by the equation y = 3 cos(π/4 - 2ωt). The motion of the particle is
A
simple harmonic with period 2π/ω
B
simple harmonic with period π/2ω
C
periodic but not simple harmonic
D
non-periodic.
Correct Answer
Option B
Detailed Explanation
The given equation y = 3 cos(π/4 - 2ωt) represents a simple harmonic motion with angular frequency 2ω. The period T is given by T = 2π/(2ω) = π/2ω, indicating simple harmonic motion with this period.
