Question

Which of the forces involved in dragging a heavy object on a smooth, horizontal surface, have the same magnitude
a) the horizontal applied force.
b) gravitational force.
c) reaction forcein vertical direction.
d) force of friction.​

Answer 1

Reaction force in vertical direction and gravitational force have the same magnitude. Force of friction is zero since its a smooth surface.

Answer 2

HII THERE IS YOUR ANSWER

"""""""""""""""""""""""""""""""""""""""""""""""

THERE ARE TWO FORCES INVOLVE IN GENERATING THE MOTION OR YOU CAN SAY HELP IN DRAGGING THE OBJECT IN HORIZONTAL SURFACE AND THESE FORCES ARE AS FOLLOWS:-

1.THE HORIZONTAL APPLIED FORCE WHICH IS RESPONSIBLE FOR GENERATING THE UPWARD ACCELERATION WHICH IS RESPONSIBLE FOR GENERATING MOTION IN THE BODY

2.REACTION FORCE IN VERTICAL DIRECTION BECAUSE IF NO FORCE IS APLLIED BY THE SURFACE THAN THE GRIP BETWEEN THE SURFACE AND THE BODY IS NOT POSSIBLE
