Force acting on a particle moving in a straight line varies with the velocity of the particle as $F = \frac{K}{\upsilon }$  where $K$ is a constant. The work done by this force in time $t$ is

  • A

    $\frac{K}{{{\upsilon ^2}}}t$

  • B

    $2Kt$

  • C

    $Kt$

  • D

    $\frac{{2Kt}}{{{\upsilon ^2}}}$
