उत्तर
The reading of a Vernier caliper is given by:
Measured Length = Main Scale Reading (MSR) + (Vernier Coincidence (VC) × Least Count (LC))
Given:
- Main Scale Reading (MSR) = 7 cm
- Vernier Coincidence (VC) = 6
- Least Count (LC) is generally 0.01 cm (assuming typical calipers).
Step 1: Calculate the Measured Length
Measured Length = 7 + (6 × 0.01)
Measured Length = 7 + 0.06 = 7.06 cm
Step 2: Find the Radius
The diameter of the ball is 7.06 cm, so the radius is:
`"Radius" = "Diameter"/2 = 7.06/2 = 3.53 cm`
The radius of the ball is 3.53 cm.

What do you mean by zero error of a screw gauge? How is it accounted for?
Figure shows the position of vernier scale while measuring the external length of a wooden cylinder.
- What is the length recorded by the main scale?
- Which reading of vernier scale coincides with the main scale?
- Calculate the length.
(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.
