Question
If the Zero error of a Vernier Caliper is zero, then
Open in App
Solution
The correct option is A Measured length = actual length
Measured length for an equipment can have zero error in them. However, this can be adjusted by subtracting the zero error from the measured value.
Hence,
L=M−Z
where:
L: Actual Length
M: Measured length
Z: Zero error
It is given zero error is zero. Hence, measured length is equal to the actual length.
It may be noted that zero error can be either positive or negative and the sign of zero error should be considered carefully.
