Question

How to calculate the least count of the spring balance which have range 100 and no. of divisions is 20

Answer 1

Least count of a measuring instrument is the least value of physical quantity that can be measured accurately using the instrument.

For example,

Take a spring balance whose range is 0-25kg. In this scale, you can see that the 1kg is divided into 10 equal parts. Therefore, the least value it can measure is 100g which can be found out by,

Measurement=1kg

Number of divisions=10

Least count=1/10 =0.1kg or 100g

Hence 100g is the least count of this instrument.

In the similar way you can find the least count of different spring balances of different range.

Answer 2

Least count = range/no. Of divisions (range divided by no. Of divisions)

There fore here least count will be

Least count= 100

=5 Ampere or mili ampere (as per the question)

I hope it will help u buddy.

Pls mark it as brainliest ans brother.
