An inextensible string passing over a smooth pulley connects two blocks of masses $m_1$ and $m_2$ $(m_2 > m_1)$ vertically. If the acceleration of the system is $(\frac{g}{n})$, then the ratio of masses $(\frac{m_2}{m_1})$ is

  • A
    $\frac{n}{n+1}$
  • B
    $\frac{n}{n-1}$
  • C
    $\frac{n+1}{n-1}$
  • D
    $\frac{n+1}{n}$
