Question

if 25th division of vernier scale coincide with 20th division of man scale, then the least count of vernier calliper is (Take 1MSD =1mm) ????

Answer 1

here is your answer. 0.2 mm

Answer 2

Concept

Vernier caliper is a measuring device used to measure line size. It is also used to measure the diameters of round objects with the help of measuring columns.

Given

25th division of vernier scale coincide with 20th division of man scale is given.

Find

We need to find the least count of vernier calliper

Solution

It is given that

25VSD = 20MSD

Therefore

1VSD = 20/25 MSD

It is given that 1MSD = 1mm

Therefore , 20*1/25

=4/5

The least count = 1MSD - 1 VSD

= 1-0.8

=0.2mm

Hence the least count is 0.2mm
