The main scale of a vernier callipers has n divisions/cm. n divisions of the vernier scale coincide with (n – 1) divisions of main scale.
(D) \(\frac{1}{n^2}\) 1 V.S.D. = \(\frac{(n-1)}{n}\) M.S.D. LC. = 1 M.S.D. – 1 V.S.D. = 1 M.S.D. – \(\frac{(n-1)}{n}\) M.S.D. = \(\frac{1}{n}\) M.S.D. = \(\frac{1}{n}\times\frac{1}{n}\) cm ∴ L.C. = \(\frac{1}{n^2}\) cm
