Question

On bringing the two jaws of a vernier callipers together, the 6th division of vernier scale coincides with the main scale. If the least count of the vernier callipers is 0.01 cm, then its zero error is: (1) +0.06 cm (2) +0.6 cm (3) +0.006 cm (4) +0.001 cm

Answer

+0.06 cm

Reason — Zero error = +6 × Least count

= +6 × 0.01 = 0.06 cm
