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 ( C 1 ) has 10 equal divisions that correspond to 9 main scale divisions. The Vernier scale of the other caliper ( C 2 ) has 10 equal divisions that corresponds to 11 main scale divisions. The readings of the two calipers are shown in the figure. The measured values (in cm) by calipers C 1 and C 2 , respectively, are:
