Question

If the value of two minimum division of linear scale is 1mm and the number of Vernier

scale division is 20, what is the Vernier constant in cm?​

Answer 1

Explanation:

1 main scale or linear scale division(M.S.D)

= 1 mm

20 Vernier scale division(V.S.D.)= 19 M.S.D.

1 V.S.D.= 19/20 M.S.D. = 0.95 mm.

Vernier Constant, V.C.= 1 M.S.D.-1 V.S.D

= (1-0.95) mm = 0.1 mm = 0.05cm.
