Assertion : The elastic spring force arises due to the net attraction or repulsion between the neighbouring atoms of the spring when it is elongated of compressed. Reason : The laws of derived forces such as spring force, friction force are independent of the laws of fundamental forces in nature.

Assertion : The elastic spring force arises due to the net attraction

1.	Assertion : The elastic spring force arises due to the net attraction or repulsion between the neighbouring atoms of the spring when it is elongated of compressed. Reason : The laws of derived forces such as spring force, friction force are independent of the laws of fundamental forces in nature.
Answer» If both ASSERTION and reason are true and reason is the CORRECT explanation of assertion. If both assertion and reason are true but reason is not the correct explanation of assertion. If assertion is true but reason is FALSE. If both assertion and reason are false. Solution :The laws of derived forces such as spring force, FRICTION are not independent of the laws of fundamental forces in NATURE. So the reason is false.
