A box is sitting on the floor. The box was then pulled with a force, Ft. The box did not move. The free-body
diagram of the box is shown.
Which describes the motion of the box based on the
resulting free-body diagram?
It is moving up with a net force of 20 N.
It is moving to the right with a net force of 10 N.
It is in dynamic equilibrium with a net force of O N.
It is in static equilibrium with a net force of O N.
F, = 20 N
F, = -10 N
F, = 10 N
F = -20 N
