What is the least count of a spring balance?

Solution

Determine the least count of a spring balance.
A least count of an instrument is the smallest value of a physical quantity that can be measured properly by using the instrument.
For example, with a spring balance with a range of $0 t o 25$ kilograms, each kilogram on the scale is split into ten equal pieces.
Therefore, the minimum value this could measure is one hundred grams, which may be calculated as follows:
Measurement $= 1 k g$
Total Number of divisions $= 10$
Least count $= (\frac{1}{10}) = 0.1 k g (o r 100 g)$
Mostly as result, the lowest count of this instrument is $100 g$ . Similarly, the least counts of different spring balances with varied ranges may be discovered.
Hence, the least count of a measurement device is the smallest physical amount that can be measured reliably using the instrument.
