Answer 2

Procedure to study Newton's law of Motion in the laboratory-

1. take two spring balances of different ranges and  marked as A and B.
2. the least count of the spring balances was noted.
3. the ring of spring balance A is fixed on a hook fixed in the wall and the spring balance B is fixed to the hook of spring balance A.
4. keep the spring balances horizontally to the table.
5. Pull the ring of spring balance B gently.
6. Observe and note the reading of both the spring balances and repeat it by applying different forces.

Observations:

1. Least count of the spring balance = Value of 1 small division
2. Least count of the spring balance A= ______ N
3. Least count of the spring balance B= ______ N

Result:

The reading of the both balances are same in every time the force changes. Thus, action and reaction forces are equal and opposite.
