Question

Assertion: If a spring is stretched from one side, the size and the shape of the spring changes. Reason: force acting on the spring changes the size and shape of the spring in the direction of application of force.​

Answer 1

A stretching force of 1 N is applied at one end of a spring balance and an equal stretching froce is applied at the other end at the same time. The reading on the balance will be

ANSWER

When we apply force 1N on one side, spring balance will get accelerated in direction of that force.

To get the reading on spring balance, we must apply equal and opposite force on other end.

In case of actual reading, suppose spring balance is hung from support, when we put mass in pan, same reaction as that of weight is applied by spring balance on support.

So, in equilibrium, if we apply force F on both sides of balance, then it will read as "F".

Here,

spring balance will now read 1N.

Answer 2

Answer:

When we apply force 1N on one side, spring balance will get accelerated in direction of that force. To get the reading on spring balance, we must apply equal and opposite force on other end. ... So, in equilibrium, if we apply force F on both sides of balance, then it will read as "F".
