10

divisions on the main scale of a Vernier calliper coincide with

11

divisions on the Vernier scale. If each division on the main scale is of

5

units, the least count of the instrument is :

Options

A $\dfrac{1}{2}$
B $\dfrac{10}{11}$
C $\dfrac{50}{11}$
D $\dfrac{5}{11}$

Correct answer

D. $\dfrac{5}{11}$

Step-by-step solution

Given:

$10MSD = 11VSD$

$⇒ 1VSD = \dfrac{10}{11}MSD$

$LC = 1MSD - 1VSD$

$= 1MSD - \dfrac{10}{11}MSD$

$= \dfrac{1MSD}{11}$

$= \dfrac{5}{11}$ units
