Question

In a Vernier Caliper given below, identify the type of zero error and Vernier scale coincidence when the jaws are closed?

a) Positive zero error, 0.1 mm
b) Negative zero error, 0.1 mm
c) Positive zero error, 0.01 mm
d) Negative zero error, 0.01 mm

Answer 1

In a Vernier Caliper, the identified type of zero error is negative and the Vernier scale coincidence is 0.1 mm when the jaws are closed.

Step-by-step explanation:

In a Vernier Caliper, when the jaws are closed and there is a zero error, it means that the jaws do not align perfectly with the zero point on the scale. In this case, the zero error is negative, indicated by the option b) Negative zero error, 0.1 mm. This means that the actual measurement is smaller than the indicated measurement on the caliper. The Vernier scale coincidence refers to the alignment of the Vernier scale with the main scale. When the jaws are closed, the coincidence value is 0.1 mm, as mentioned in option b).
