Question

The least value measured with meter-scale is (if the meter scale is divided into 1000)

Answer 1

Total length of scale$\left(L\right)$-

$L=1m$

Total no of divisions$\left(n\right)$-

$n=1000$

So least value will be equal to the value of one division.

Value of one dividion$\left(LV\right)$-

$LV=\frac{L}{n}$

$\Rightarrow LV=\frac{1}{1000}m$

$\Rightarrow LV=0.001m$

$\Rightarrow LV=1mm$

Hence, least value is one millimeter.
