In a vernier callipers if each centimetre of the main scale is divided into $q$ equal parts and $p$ vernier scale divisions coincide with $(p - 1)$ main scale divisions, then what will be the least count?

Options:

Answer:

Solution:

$1 M S D = \frac{1}{q}$

$p \times VSD = (p - 1) \times MSD$

$\Rightarrow 1 VSD = \frac{(p - 1)}{p q}$

$L . C . = 1 MSD - 1 VSD$

$\Rightarrow \frac{1}{q} - \frac{(p - 1)}{p q} = \frac{1}{p q}$
