Question

A varnier calipers having main scale of $10cm$ containing $100$ division, If $n$ be number of division on vernier scale of length $L$ Vernier calipers is designed to have a least count of $0.02cm$, then

Answer 1

$Ms-Vs=$ least count

least count on main scale = $0.1cm$

$0.1cm-Vs=0.02cm$

$0.08cm=vs$

$\therefore$ There should be 80 division of vernier scale so $n=80$
