Solution

The correct option is B added to
Negative zero error in a vernier callipers, occurs when the zero mark of the vernier scale does not coincide with that of the main scale, instead appears before it, i.e. to the left of the zero mark of the main scale.
The magnitude of the negative zero error is added to the observed length of an object measured in a vernier callipers.

Q. The magnitude of the negative zero error is added to the observed length in a vernier callipers.

Q. If the zero error of a vernier callipers is zero, then:

How is the zero error calculated in a vernier calliper?

In a vernier callipers, there are 10 divisions on the vernier scale and 1 cm on the main scale is divided in 10 parts. While measuring a length, the zero of the vernier lies just ahead of 1.8 cm mark and 4th division of vernier coincides with a main scale division.

(a) Find the length.

(b) If zero error of vernier callipers is - 0.02 cm, what is the correct length ?

Q. Assertion :A vernier callipers has a positive error of 0.5 mm, then the correction is -0.5 mm. Reason: In case of positive zero error, measured length is greater than the actual length.
