A:

Hi Kanhaiya,

A spring balance is a device used to measure the weight of an object.

A standard spring balance could be found with a scrap dealer who usually measures the weight of the newspaper or any other scrap.

Its least count is generally around 1 kg or 0.5 kg depending on the balance.

When no weight is added on the balance, the reading that it shows is called the zero error or zero balance.

To use a balance place some weight on the hook of the balance and observe the reading on the scale.

If initially the zero error was 1 kg, then whatever you measure will be more by 1 kg. So, subtract that from your observed value.
