Question

The Vernier scale of a travelling microscope has 50 divisions which coincides with 49 main scale divisions. If each main scale division is 0.5 mm, then the lease count of the microscope is (A) 0.01 mm (B) 0.5 cm (C) 0.01 cm (D) 0.5 mm

Tardigrade Admin · Accepted Answer

L . C =1 MSD -1 VSD or L.C =(1 MSD / text No.of.vernier scale division )=(0.05 mm /50) L.C =0.01 mm

Q. The Vernier scale of a travelling microscope has $50$ divisions which coincides with $49$ main scale divisions. If each main scale division is $0.5 mm$ , then the lease count of the microscope is

0.01 mm

0.5 cm

0.01 cm

0.5 mm

$L . C = 1 MS D - 1 V S D$
or L.C $= \frac{1 MS D}{No.of.vernier scale division} = \frac{0.05 mm}{50}$
L.C $= 0.01 mm$
