Answer:
The box will move with a constant velocity if no
net external force acts on the body. Thus, the effect of force of friction has
to be balanced.
So a force equal to
the force of friction i.e., 200 N but opposite in direction has to be applied
on the box to move it with a constant velocity. So the applied force on the box
is 200 N.
