Question

A spring balance is pulled at it's both end by 10 kg what is the reading of spring balance?

Answer 1

If a force is applied to the weighing end of a spring balance, and no force is applied to the other end, the spring balance will accelerate in the direction of the applied force. To measure a force on a spring balance, an equal and opposite force must always be applied to the other end. If the spring balance is hung from a fixed point, the necessary force is transmitted through the spring balance.

When a stretching force of 10N is measured on a spring balance, the same stretching force is applied to opposite ends at the same time. The reading is 10N

So g = 9.8 m/s²

so the spring balance will show the weight i.e. = mg = 10 x 9.8 = 98 N

Answer 2

Answer:

100

Explanation:

As we are applying same force on both sides then the spring balance reading will show the same reading as it is not accelerating anywhere.

But in case it asks weight then it is 10 gravity and 10 newton.

So answer is almost 100.
