Two balls of mass $M$ and $2M$ are thrown horizontally with the same initial velocity $v_{0}$ from the top of a tall tower and experience a drag force of $-kv$ $(k > 0)$,where $v$ is the instantaneous velocity. Then,

  • A
    the heavier ball will hit the ground further away than the lighter ball
  • B
    the heavier ball will hit the ground closer than the lighter ball
  • C
    both balls will hit the ground at the same point
  • D
    both balls will hit the ground at the same time
