Question

Distinguish between physical balance and beam balance

Answer 1

In principle, it is just a common balance where there are two pans and you measure weight of an object by putting it in one pan and a known weight in the other.

A physical balance is a very sensitive common balance which can measure weights in milligram order. It is placed in a protective glass case so that even dust and wind can’t affect the accuracy of the instrument.
