Answer 2

Given : Four instruments measured the diameter of a wire whose values are given below.

Instrument 1 → 1.3 mm

Instrument 2 → 1.32 mm

Instrument 3 → 1.324 mm

Instrument 4 → 1.03 mm

To Find :

The instrument having smallest value of least count is

(a) Instrument 1

(b) Instrument 2

(c) Instrument 3

(d) Instrument 4​

Solution:

Least Count :

The smallest value up to which an instrument can measure .

Instrument 1 → 1.3 mm   can measure upto 1 decimal place

Instrument 2 → 1.32 mm   can measure upto 2 decimal place

Instrument 3 → 1.324 mm   can measure upto 3 decimal place

Instrument 4 → 1.03 mm  can measure upto 2 decimal place

Instrument 3 can measure upto 3 decimal places

Hence  The instrument having  smallest value of of least count is   Instrument 3
