Question

A student has used a vernier caliper with LC 0.01cm to measure the length of his pencil.He found that main scale showed reading of 8.3cm and vernier scale coincides with 5th position to main scale.Give correct measurement of the length of pencil neglecting zero error.

Answer 1

Answer:

Measurement of the length of pencil neglecting zero error is 8.35 CM.

Explanation:

Considering that,

Perusing if the pencil when estimated = 8.3cm.

Vernier Callipers Least count = 0.01cm

Furthermore, considering that it concurs with

fundamental scale perusing at 5th division.

Then,

Noticed length = main scale reading + ( Vernier scale

concurs with any of the main scale reading × Least

count)

I. e., = 8.3 + (5 × 0.01)

= 8.3 + 0.05

= 8.35 CM.
