Question

Assertion : As per newtons third law , resultant of action and reaction is not equal to zero reason : Action and reaction acts on different bodies

Answer 1

Answer :

Both Assertion and reason are true and the reason is the correct explanation of the assertion $\sf .$

━━━━━━━━━━━━━━

• Newton's third law states that " Every Action has an equal and opposite reaction and they act on two different bodies"

• Say a horse is tied to a cart. So for the cart to move the horse applies a force against the ground and as an opposite reaction the horse moves. As the horse moves it applies a force on the cart and if the cart applies a equal and opposite force then the cart would never move and this isn't true

• This is because the opposing force is on the horse and not on the cart and hence moving it.

• This incident proves us that the resultant force is not zero as the the forces act on different bodies

Answer 2

Answer:

$\mapsto$ The action and reaction force are equal in magnitude and opposite in direction. Therefore, their sum is zero they act on different bodies.

Hence, the explanation is correct.

Explanation:

$\implies$ For every action there is an equal and opposite reaction.

The above statement means that in every interaction, there is an pair of forces acting on the two reacting objects. The size of the forces on the first object equal the size of the force on the second object. The direction of the force on the first objectis opposite of the second object. Force always comes in pair equal and opposite action and reaction force pairs.
