Answer 2

1.2 mm is the correct thickness of the pencil.

Explanation:

Given that,

Measured thickness = 1.4 mm

Zero error of vernier callipers = +0.02 cm

To find,

correct thickness of the pencil = ?

Procedure:

Correct thickness of the pencil = measured thickness – correction/error

= 1.4 mm - (+0.02 cm)

= 1.4 mm - 0.2 mm

= 1.2 mm

Thus, option b i.e. 1.2 mm is the correct answer.
