Question 218: Units , Dimensions and Error Analysis

Question

The Vernier constant of Vernier callipers is 0.1 mm and it has zero error of ($$-$$0.05) cm. While measuring diameter of a sphere, the main scale reading is 1.7 cm and coinciding vernier division is 5. The corrected diameter will be _________ $$	imes$$ 10
$$-$$2
cm.

Accepted Answer

Since zero error is negative, we will add 0.05 cm.
$$\Rightarrow$$ Corrected reading = 1.7 cm + 5 $$	imes$$ 0.1 mm + 0.05 cm
= 180 $$	imes$$ 10
$$-$$2
cm
