Question

If the Zero error of a Vernier Caliper is zero, then

• A. measured length = actual length
• B. measured length > actual length
• C. measured length < actual length
• D. measured length > = actual length

Answer 1

The correct option is A

measured length = actual length

Correct reading = observed reading - zero error (with sign).

or in this case, Actual length = measured length - zero error (with sign).

So, measured length = actual length.
