A body of weight $64\, N$ is pushed with just enough force to start it moving across a horizontal floor and the same force continues to act afterwards. If the coefficients of static and dynamic friction are $0.6$ and $0.4$ respectively, the acceleration of the body will be (Acceleration due to gravity $= g$)

  • A

    $\frac{g}{{6.4}}$

  • B

    $0.64\, g$

  • C

    $\frac{g}{{32}}$

  • D

    $0.2\, g$
