The vernier constant of a vernier callip...

The vernier constant of a vernier callipers is `0.1 mm` and it has a positive zero error of `0.04 cm`. While measuring diameter of a rod, the main scale reading is `1.2 cm` and `5th` vernier division is coinciding with any scale division. The correct diameter of the rod is

A

1.21 cm

B

1.21mm

C

1.29 mm

D

1.29 cm

Text Solution

Verified by Experts

The correct Answer is:
(a)
V.C = 0.1 mm = 0.01 cm , zero error = 0.04 cm.
Zero correction = -0.04 cm.
Observed diameter = `(1.2 +5 xx0.01)` cm
=1.25 cm
Corrected diameter =` (1.25 - 0.04)` cm
= 1.21 cm

In a vernier callipers, 10 vernier scale divisions coincide with 9MSD each of value 1mm. While measuring length of a cylinder using this calliper, main scale reading is 5.1 cm and 7th vernier division coincides with any main scale division. Whenm diameter of cylinder is measured, main scale reading is 1.7 cm and 3rd vernier division coincides with any main scale division. Calculate curved surface area of the cylinder with correct number of significant figures.
