The phase (at a time $t$) of a particle in simple harmonic motion tells:

  • A
    Only the position of the particle at time $t$
  • B
    Only the direction of motion of the particle at time $t$
  • C
    Both the position and direction of motion of the particle at time $t$
  • D
    Neither the position of the particle nor its direction of motion at time $t$

$A$ particle executes simple harmonic motion between $x=-A$ and $x=+A$. If it takes a time $T_1$ to go from $x=0$ to $x=A/2$ and $T_2$ to go from $x=A/2$ to $x=A$,then:

$A$ particle executes simple harmonic motion represented by the displacement function $x(t) = A \sin (\omega t + \phi)$. If the position and velocity of the particle at $t = 0 \, s$ are $2 \, cm$ and $2 \omega \, cm \, s^{-1}$ respectively,then its amplitude is $x \sqrt{2} \, cm$,where the value of $x$ is ..... .
