Question
A man tries to pull a heavy load but is not able to move it at all. What could be the reason for this?
- The load is too heavy
- The person is not applying sufficient force
- The person is applying force in a wrong direction
- None of the above
Hint:
If resultant force on object is zero then only it will he stationary.
The correct answer is: The person is not applying sufficient force
- If the object is stationary then this can be due to following reason.
- No Force is applied on the object.
- Resultant force is zero that is friction force or some other force is sufficient to balance the force applied by the man so man's force is insufficient.
