The least count of given Vernier Calipers is

L C = MS D - V S D = 1 - (9/10) = 0.1 mm

The main scale reading is

MS R_{0} = 0 mm

and the Vernier scale reading is

V S R_{0} = 3.

Thus,
Zero Error

= MS R_{0} + V S R_{0} \times L C

= 0 + 3 \times 0.1 = 0.3 mm

Q. The jaws of the Vernier callipers shown in figure are in contact with each other. The zero error of this Vernier calipers is 10x​mm . Find x .

The least count of given Vernier Calipers is LC=MSD−VSD=1−(9/10)=0.1mm The main scale reading is MSR0​=0mm and the Vernier scale reading is VSR0​=3. Thus, Zero Error =MSR0​+VSR0​×LC =0+3×0.1=0.3mm

Q. The jaws of the Vernier callipers shown in figure are in contact with each other. The zero error of this Vernier calipers is $\frac{x}{10} mm$ . Find $x$ .

The least count of given Vernier Calipers is
$L C = MS D - V S D = 1 - (9/10) = 0.1 mm$
The main scale reading is $MS R_{0} = 0 mm$ and the Vernier scale reading is $V S R_{0} = 3.$ Thus,
Zero Error $= MS R_{0} + V S R_{0} \times L C$
$= 0 + 3 \times 0.1 = 0.3 mm$
