Correct option is A
The difference between
1 Main Scale Division (M.S.D) and
1 Vernier Scale Division (V.S.D) is the
least count of the Vernier caliper, which is typically
0.02 mm for a standard metric Vernier caliper.
Explanation:
Main Scale Division (M.S.D):
· The
main scale is graduated in millimeters or inches.
· On a standard metric Vernier caliper,
1 M.S.D = 1 mm.
Vernier Scale Division (V.S.D):
· The Vernier scale is a secondary scale located on the sliding jaw.
· It is designed so that a specific number of V.S.Ds are slightly smaller than the corresponding number of M.S.Ds.
Difference Between M.S.D and V.S.D:
· The difference between
1 M.S.D and
1 V.S.D is the least count of the caliper.
