Question

Name the two scale of a vernier calliper and explain how it is used to measure the length correct up to 0.01cm

Answer 1

Answer:

The main scale is graduated to read up to 1 mm and on vernier scale, the length of 10 divisions is equal to the length of 9 divisions on the main scale. Thus, L.C. = 1 mm /10 = 0.1 mm = 0.01 cm. Hence, a vernier callipers can measure length correct up to 0.01 cm.
