Two simple harmonic motions are represented by the equation y1=0.1\mathrm{y}_1=0.1 sin⁡\sin\left(100 \pi t+\frac{\pi}{3}\right)andandy_2=0.1 \cos \pi t. The phase difference of the velocity of particle 1 w.r.t. the velocity of the particle 2 is

Options

  1. A−π/6-\pi / 6
  2. Bπ/3\pi / 3
  3. C−π/3-\pi / 3
  4. Dπ/6\pi / 6

Correct answer

A. −π/6-\pi / 6

Step-by-step solution

Phase difference (ϕ)=99πt+π/3−π/2(\phi)=99 \pi \mathrm{t}+\pi / 3-\pi / 2 at t=0,ϕ=−π/6t=0, \phi=-\pi / 6.
