A particle of mass mmm is initially at rest at the origin. It is subjected to a force and starts moving along the xxx-axis. Its kinetic energy KKK changes with time as dK/dt=γt,dK/dt = \gamma t,dK/dt=γt, where γ\gammaγ is a positive constant of appropriate dimensions. Which of a positive constant of appropriate dimensions. Which of the following statement is (are) true?
  1. A
    The force applied on the particle is constant
  2. B
    The speed of the particle is proportional to time
  3. C
