Question

Find the actual reading if the main scale reading is 6 CM, vernier scale coincidence is 8 and zero error is + 0.03​

Answer 1

Answer:

0.1 mm

Least count error

A metre ruler may have graduations at 1 mm division scale spacing or interval. A Vernier scale on a caliper may have a least count of 0.1 mm while a micrometer may have a least count of 0.01 mm.

Answer 2

Answer:

6.05 cm

Explanation:

measuring instrument = Vernier Calipers

L. C = 0.01 cm

Zero Error = + 0.03cm

Actual Reading = Main Scale Reading + Vernier Reading × LC - (+ve)Zero Error

Actual Reading = 6 + 8 × 0.01 - 0.03

Actual Reading = 6.05 cm
