The main scale of a vernier callipers has n divisions/cm. n divisions of the vernier scale coincides with (n-1) divisions of main scale. The least count of vernier callipers is 1) 1/(n+1)(n-1) cm. 2). 1/n cm. 3) 1/n^2. Cm 4) 1/n(n+1). Cm

Answer:
2. 1/n
Explanation:
Given, N Vernier Scale Divisions(VSD)=(N−1)Main Scale Divisions(MSD)
1 VSD=(N−1/N) (MSD)
L.C= Least count =1MSD−1VSD
L.C=[1− (N−1/N)](MSD)
= 1/N(MSD)
MSD is per Cm
therefore,
LC = 1/N
