The phase difference between displacement and velocity of a particle in simple harmonic motion is
- A \(\pi \mathrm{~rad}\)
- B \(3 \pi / 2 \mathrm{~rad}\)
- C zero
- D \(\pi / 2 \mathrm{~rad}\)
Answer & Solution
Correct Answer
(D) \(\pi / 2 \mathrm{~rad}\)
Step-by-step Solution
Detailed explanation
The displacement of a particle in simple harmonic motion is given by \(x(t) = A \sin(\omega t + \phi)\). The velocity of the particle is the time derivative of displacement, \(v(t) = \dfrac{dx}{dt} = A \omega \cos(\omega t + \phi)\). Using the trigonometric identity…
