What is the free body diagram of the box pushed by a man on a surface?

Options:


Man pushing a box

Option:



Correct Answer: a.

Explanation:

Free Body Diagram (FBD) is a simple diagram which shows the magnitude and directions of all the forces acting on an object or a system. To construct FBD we have to determine all the forces acting on the object and the direction that each force is acting. In the above example a man is pushing the box in forward direction therefore the applied force is acting in right hand side direction that is forward and the friction force is acting exactly opposite to it. The box has weight, thus the gravitational force is acting in the downward direction and the normal reaction is acting in upward direction.
