The vernier scale of a travelling microscope has 50 division which coincide with 49 main scale division. If each main scale division is 0.5 mm, calculate the minimum inaccuracy in the measurement of distance.

Explanation

Given, 50 VSD = 49 MSD
` implies 1 VSD= ((49)/(50))MSD`
Minimum inaccuracy in the measurement of distance = least count of the travelling microscope.
= 1MSD - 1VSD
` 1 MSD -((49)/(50)) MSD = (1)/(50) MSD= (1)/(50)xx0.5mm`
`=0.01mm`
