Question

A man makes a ruler with graduation in cm i.e 100 divisions in 1m on it. To what accuracy can this ruler measure? how can this accuracy be increased?​

Answer 1

Let's find the shortest distance possible

To calculate we need the length per division divide total length by divisions

• 1/100m
• 0.001m
• 0.1cm
• 1mm

Till 1 mm it can measure

To increase accuracy increase no of divisons
