There are two Vernier calipers both of which have
1 cm divided into
10 equal divisions on the main scale. The Vernier scale of one of the calipers
(C1) has
10 equal divisions that correspond to
9 main scale divisions. The Vernier scale of the other calipers
(C2) has
10 equal divisions that correspond to
11 main scale divisions. The readings of the two calipers are shown in the figure.
