Question

Physical balance measure small difference in mass up to

Answer 1

Physical balances are an old fashioned form of a weight measuring instrument. It is slightly inaccurate in its calculation since it uses only a relative method of measurement.

 

The small difference in its measurement is also referred to as the least count of the instrument. In the case of a physical balance, it depends on the substance which it is supposed to measure and also the unit employed in weighing. Several companies use varying systems of weight measurement including pound and kilogram.

 

Thus, the least count of mass measurement is not a fixed value and can vary up to a certain extent.
