Question

the least count of the three instruments are 1mm, 0.1mm,and 0.01mm. which one has the greater precision

Answer 1

As least count decreases precision increases

in the given question the instrument with least count 0.01mm will have greater precision

Answer 2

Given:

The least count of three instruments

1 mm , 0.1 mm , 0.01 mm

To Find:

which one will have the greatest precision

Explanation:

The smallest measurement that can be taken by a measuring instrument is the least count.

The value of precision depends on the least count of the instrument as the least count is lesser the value of precision will be higher

So therefore the instrument having precision 0.01mm will be more precise

Hence Answer = 0.01mm
