Q 2) In a vernier calliper n divisions on the main scale correspond to n+1 no the vernier scale. Each division of the vernier scale is of a unit.
What is the least count?
106Q2 .
1 vernier scale division = a
==> n+1 VSD = (n+a)a
==> n MSD = a(n+1)
==> 1 MSD = a(1+1/n)
==> LC = a + a/n - a = a/n
106Q1.
1 MSD = a
n MSD = an
n+1 VSD = an
1 VSD = an/(n+1)
==> LC = a - an/(n+1)
= (an +a -an)/(n+1)
= a/(n+1)
