Solution
Pitch of the screw= 0.5 mm
No. of divisions on circular scale = 50
`"Least count"="pitch of the screw"/"no. of divisions on the circular scale"`
so, L.C. = `0.5/50=0.01` mm

While measuring the length of a rod with a vernier callipers, below shows the position of its scales. What is the length of the rod?
(a) A vernier scale has 20 divisions. It slides over the main scale, whose pitch is 0.5 mm. If the number of divisions on the left hand of the zero of vernier on the main scale is 38 and the 18th vernier scale division coincides with the main scale, calculate the diameter of the sphere, held in the jaws of vernier callipers.
(b) If the vernier has a negative error of 0.04 cm, calculate the corrected radius of the sphere.
