Third Law of Motion: Practice Problem & Solution

When a horse pulls a cart, the force that helps the horse to move forward is the force exerted by
the cart on the horse
the ground on the horse
the ground on the cart
the horse on the ground

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:

Horse applies force on earth at certain angle. In turn earth apply force on horse horizontal component of this force helps the horse and cart to move forward.

2. 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.  
3. Assertion (A): A block is hanging from spring. Spring force on block and gravitational force on block are not action and reaction pair. Reason (R): Action and reaction force acts in opposite direction.  
4. Assertion (A): An air tight cage in which a bird is sitting, is suspended from a spring balance. If the bird starts flying upwards with some acceleration, then the reading of the balance will increase. Reason (R): The weighing machine measures the actual weight of a body.  
5. 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.
