I would say the Third law based on what I copied below

The rate of change of momentum is directly proportional to the impressed force and takes place in the same direction in which the force acts”.3. Newton's Third law

 

First law:When viewed in an inertial reference frame, an object either remains at rest or continues to move at a constant velocity, unless acted upon by an external force.

Objects in motion tend to stay in motion, and objects at rest tend to stay at rest unless an outside force acts upon them.

Second law:The vector sum of the forces F on an object is equal to the mass m of that object multiplied by the acceleration vector a of the object: F = ma.

The rate of change of the momentum of a body is directly proportional to the net force acting on it, and the direction of the change in momentum takes place in the direction of the net force.

Third law:When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body.

To every action (force applied) there is an equal but opposite reaction (equal force applied in the opposite direction).

Always good questions that refresh our minds and make scientific discussion.But The answer is "B" .Thanks Mr. Al Yazouri and Mrs.Woofter

 

Definitely Newton Third Law, which describe well with Elke answer.

Alex Al Yazouri
by Alex Al Yazouri , General Manager , Al Mushref Cooperative Society

The correct answer is

B  Newton's second law of motion

 

Second law: The vector sum of the forces F on an object is equal to the mass m of that object multiplied by the acceleration vector a of the object: F = ma.

""The rate of change of the momentum of a body is directly proportional to the net force acting on it, and the direction of the change in momentum takes place in the direction of the net force.""

 

Please read Elke's answer well and read the question again.

I just realize that I forgot that basic of physics. Thanks for reminding me.

Yes it is3rd Newton's law

I think you refer to the Third law of Sir Newton
