The velocity vector $v$ and displacement vector $x$ of a particle executing $SHM$ are related as $\frac{v dv}{dx} = -\omega^2 x$ with the initial condition $v = v_0$ at $x = 0$. The velocity $v$,when displacement is $x$,is

  • A
    $v = \sqrt{v_0^2 + \omega^2 x^2}$
  • B
    $v = \sqrt{v_0^2 - \omega^2 x^2}$
  • C
    $v = \sqrt[3]{v_0^3 + \omega^3 x^3}$
  • D
    $v = v_0 - (\omega^3 x^3 e^{x^3})^{1/3}$
