Question

The following information is given in respect of the vernier caliper

Main scale division = 0.3cm , 30 VSD = 29 MSD. The least count of this vernier caliper is …..

a )0.01mm

b)0.1cm

c)0.03cm

d)0.1mm​

Answer 1

Answer:

d.

Explanation:

1 MSD=0.3 cm

since,30 VSD=29 MSD

(i.e.,N VSD =(N-1) MSD)

least count

=(1MSD)/(30)=(0.3cm)/(30)=0.01 cm= 0.1 mm

Answer 2

Answer:

D is the correct answer

Explanation:

1 MSD = 0.3 cm

Since, 30 VSD = 29 MSD

(i.e., N VSD = (N-1) MSD)

Least count

= 1MSD30=0.3cm30 = 0.01 cm = 0.1 mm
