Question

12. For the given part of Vernier caliper calculate zero error. 45 40 35 30 (MSR) 10 5 0 (VSR) so, in this question is there is positive zero error or negative zero error?​

Answer 1

The Vernier caliper is an instrument that allows you measure lengths much more accurate than the metric ruler. The smallest increment in the vernier caliper you will be using is (1/50)mm = 0.02mm = 0.002cm. Thus, the uncertainty is ∆x = (1/2)0.002 cm = 0.001 cm.
