Third Law of Motion: Practice Problem & Solution

A car accelerates on a horizontal road due to the force exerted by
the engine of the car
the driver of the car
the earth
the road

Solution Explained:

To solve this problem, we apply the core principles of Third Law of Motion. Understanding the underlying formula is key to arriving at the correct answer below:

Friction force applied by road on the car act in the direction of the motion which is responsible to move the car.

1. Assertion (A): A man standing at rest on ground. Force exerted by man on ground is equal to weight of man. Reason (R): Earth attracts man by force \(mg\) hence by Newton's third law, man also attracts earth by same force.  
2. Assertion (A): According to Newton's third law of motion, action and reaction forces are equal in magnitude and opposite in direction. Reason (R): Net force on a body due to action-reaction pair is always equal to zero.  
3. In a general debate on topic "normal reaction and mg never form action and reaction pair" a number of students  took part :- (I) Navneet said – Action and reaction forces should be of same nature (II) Anand said - Action and reaction forces act on two different bodies here, normal reaction and mg both are acting on the block. (III) Meenakshi said – Action and Reaction forces balance each other. So, normal reaction and mg should be action and reaction pair. Mark correct option as your judgement 
4. Assertion (A): According to the Newton's third law of motion, the magnitude of the action and reaction force in an action reaction pair is same only in an inertial frame of reference. Reason (R): Newton's laws of motion are applicable only in inertial reference frame.  
5. If action force is gravitational force, then reaction force :
