In the figure shown, a block of weight $10 \,N$ resting on a horizontal surface. The coefficient of static friction between the block and the surface ${\mu _s} = 0.4$. A force of $3.5\, N$ will keep the block in uniform motion, once it has been set in motion. A horizontal force of $3 \,N$ is applied to the block, then the block will

  • A

    Move over the surface with constant velocity

  • B

    Move having accelerated motion over the surface

  • C

    Not move

  • D

    First it will move with a constant velocity for some time and then will have accelerated motion
