19MSD = 20VSD ∴ Least count =(MSD/20)=0.1 mm ⇒ MSD=2 mm

Q. A vernier caliper has $20$ divisions on the vernier scale which coincide with $19$ divisions on the main scale. The least count of the instrument is $0.1 mm$ . The main scale divisions are _____ mm

$19 MS D = 20 V S D$
$∴$ Least count $= \frac{MS D}{20} = 0.1 mm$
$\Rightarrow MS D = 2 mm$
