### Question

During Searle’s experiment, zero of the Vernier scale lies between and of the main scale. The division of the Vernier scale exactly coincides with one of the main scale divisions. When an additional load of is applied to the wire, the zero of the Vernier scale still lies between and of the main scale but now the division of Vernier scale coincides with one of the main scale divisions. The length of the thin metallic wire is and its cross – sectional area is . The least count of the Vernier scale is . The maximum percentage error in the Young’s modulus of the wire is.

### Question

There are two Vernier calipers both of which have divided into equal divisions on the main scale. The Vernier scale of one of the calipers has equal divisions that correspond to main scale divisions. The Vernier scale of the other caliper has equal divisions that correspond to main scale divisions. The readings of the two calipers are shown in the figure. The measured values (in cm) by calipers and , respectively, are:
