Question

Suppose the least count of a Vernier scale is 0.01cm. While measuring the diameter of a metallic ball,

we get main scale reading is 6.4cm and 3rd division of Vernier scale coincides with a main scale

division. Calculate the diameter of the metallic ball​

Answer 1

Hi ! Using the formula MSR + (L.C x VSD )

6.4 + (0.01 x 3)

6.4 +0.03

6.43 cm

Hope this helps
