callipers 7 How is it determined ? Draw neat
diagrams to explain it How is it taken in account
to get the correct measurement ?​

Answer 1

Answer:The vernier calliper which shows accurate measurements is said to be having zero error.To see whether the vernier calliper has zero error,the 0 on the vernier scale should match with the 0 on the main scale.

Explanation:plz mark it is a brainliest

Answer 2

Initially when the zeroth division on the vernier scale does not coincide with the zeroth division on the main scale, the vernier calipers has zero error. It can be either positive or negative.

To calculate positive zero error,multiply the coinciding division with the least count of vernier calipers. To calculate negative zero error,subtract the coinciding division from the total number of divisions on vernier scale and then multiply the difference by the least count.
