Question

In the measurement of the length of a cylinder, the main scale reading of a vernier caliper is 2.8 cm, the vernier reading is 4, and the least count of the vernier is 0.01 cm. Find the reading of the length of the cylinder.

Answer 1

the reading of the length of the cylinder is 2.84 cm

Explanation:

Given the data in the question;

the main scale reading = 2.8 cm

the Vernier reading = 4

the least count of the Vernier = 0.01 cm

the reading of the length of the cylinder = ?

To determine the reading of the length of the cylinder, we simply say;

Reading length = main scale reading + ( Vernier reading × least count )

so we substitute in our given values

Reading length = 2.8 cm + ( 4 × 0.01 cm )

Reading length = 2.8 cm + 0.04 cm

Reading length = 2.84 cm

Therefore, the reading of the length of the cylinder is 2.84 cm
