The smallest division on the main scale of a Vernier callipers is $$1$$ mm and $$10$$ vernier divisions coincide with $$9main$$ scale divisions. While measuring the diameter of a ring the zero mark of the vernier scale lies between $$5.0$$ cm and $$5.1$$ cm and the eighth division of the vernier scale coincides with a main scale division. The diameter of the ring is (in$$ $$cm)

Question

Infinity Learn · Accepted Answer

$$LC=0.1mm=0.01cmReading$$ $$=$$ main scale reading $$+$$ vernier scale reading $$=$$ $$5.0$$ $$+$$ (8)(0.01) $$=$$ $$5.08$$ cm.

Measurement

Remember concepts with our Masterclasses.

LC=0.1mm=0.01cm
Reading = main scale reading + vernier scale reading = 5.0 + (8)(0.01) = 5.08 cm.
