The maximum velocity of the photoelectron emitted by the metal surface is $V$. The charge and mass of the photoelectron are denoted by $e$ and $m$ respectively. The stopping potential in volts is:

  • A
    $\frac{V^{2}}{(m/e)}$
  • B
    $\frac{V^{2}}{2(e/m)}$
  • C
    $\frac{V^{2}}{(e/m)}$
  • D
    $\frac{V^{2}}{2(m/e)}$
