d) None of these
5 .For every action, there exists equal and opposite reaction, this is
a) Newton's first law
b) Newton's second law
c) Newton's third law
d) None of these​

Answer 1

2. Both A and B are true

3.Movement of rocket is possible due to the third law of motion.

4 the vertical component of the reaction balances our weight.

5. It is an example of the third law of Newton.

Explanation:

• when we put our feet on the ground there is an equal and opposite reaction. The reaction has a vertical component and horizontal component. The vertical component helps in equalization and Neutralization of the weight of our body.
• Whereas the horizontal component helps our body to move in the forward direction. This is in accordance to the third law of Newton.
