  • A farm tractor is pulling a wagon. The tractor is three times heavier than the wagon. The tractor starts from rest and accelerates for a short while. The magnitude of the force with which the wagon pulls on the tractor is

  • Zero.

  • One-third of that with which the tractor pulls on the wagon.

  • Equal to that with which the tractor pulls on the wagon.

  • Three times that with which the tractor pulls on the wagon.
