Question

When you and your friend push a table in the opposite direction, it becomes difficult to move. This is because the net force becomes the difference of the two forces.
(A) True
(B) False

Answer 1

When two forces act equal and opposite to each other and the magnitude of forces are equal, then the net force is zero. Hence, the net force will be equal to the difference between those two forces. Here also a similar case occurs. That is, when two persons push a table just in the opposite direction the resultant net force will be their difference.

Complete step by step answer:
When two forces act equal and opposite to each other and the magnitude of forces are equal, then the net force is zero. Hence, the net force will be equal to the difference between those two forces. Here also a similar case occurs. That is, when two persons push a table just in the opposite direction the resultant net force will be their difference.
Thus, the given statement is true.

Therefore option (A) is correct.

Additional information:
The force acting on a body can be described as a pull or a push. In all cases there will be an interaction between two objects. When two of the forces are acting just opposite to each other, it can be also called as action and reaction. This concept is used in case of Newton’s third law.

Note:
Thus a net force can be defined as the sum of all forces acting on a body. The force is calculated using the concept of product of mass and acceleration. That is, net force is the algebraic sum of all forces acting on an object. When two forces act equal and opposite to each other and the magnitude of forces are equal, then the net force is zero. Hence, the net force will be equal to the difference between those two forces.
