Question

What will be the magnitude of net force in the following situations?
(a) In tug of war, both the teams applying equal force in opposite directions.
(b) Two boys pushing a box, each with 5N force towards east.

Answer 1

In option a the body will remain at rest or the rope will break down.The net force will be 0 acting.In the second case the box will move towards the frce as directed.
Friend i only know this much

Answer 2

• The magnitude and the net forces will be equal in both the above given situations.
• But, the force and magnitude will be in the opposite direction.
• Hence it is mentioned as a balanced force.
• They don't bring any change to the object.
• They are equal in magnitude.
• The result is always zero.
• The object remains stationary.
• They "do not need" any external force to balance, because it is already balanced.
• Example: book kept on a table
• They both are the examples of Newton's third law.
