Question

Name the instrument which is commonly used to measure the mass of a body. State how it is used?

Answer 1

Instrument commonly used to measure the mass of a body, is the beam balance.

When we hold up the balance, we observe that when there is nothing on either pan, the beam is horizontal. The body whose mass is to be measured is placed on the left pan. The standard weight are put on the right pan. They are so adjusted that the beam is again horizontal on holding the balance up. The total of the standard weights gives the mass of the given body.
