How do you apply the correction due to the zero error?
Answers
Answer:
Subtract the zero error from the measured length to get the actual length as the measured length is greater than the actual length.
Explanation:
Answer:
What is zero error ?
Its zero correction is (take L.C = 0.01cm) .
Zero error is defined as -
The condition where a measuring instrument records a reading when no reading is required.
In case of Vernier calipers it occurs when a zero on the main scale does not coincide with a zero on Vernier scale .
it is called zero error for Vernier.
Positive zero error occurs when the '0' marking of the thimble scale is below the horizontal reference line of the main scale.
The error is +x mm.
To correct the reading,
we subtract the error from the measurement.
Subtract the zero error from the measured length to get the actual length as the measured length is greater than the actual length.
