Question:

If nth division of main scale coincides with (n+1)th division of vernier scale and main scale division is equal to a mm, then Le

If nth division of main scale coincides with (n+1)th division of vernier
scale and main scale division is equal to a mm, then
Least count of Vernier calliper is 0.1 mm for a = 1 mm and
n = 9
Least count of Vernier calliper 0.1 mm for a = 2 mm and n
= 19
=
If value of n increases, then least count will also
increase
If value of n increases then least count will also
decrease

If nth division of main scale coincides with (n+1)th division of vernier scale and main scale division is equal to a mm, then Least count of Vernier calliper is 0.1 mm for a = 1 mm and n = 9 Least count of Vernier calliper 0.1 mm for a = 2 mm and n = 19 = If value of n increases, then least count will also increase If value of n increases then least count will also decrease
