In a vernier callipers, there are 10 divisions on the
vernier scale and 1 cm on the main scale is divided
in 10 parts. While measuring a length, the zero of
the vernier lies just ahead of 1.8 cm mark and 4th
division of vernier coincides with a main scale
division.
(a) Find the length
(6) If zero error of vernier callipers is -0-02 cm,
what is the correct length ?

Answer and Explanation:
No. of Divisions = 10
Main Scale Each Division = 1/10 = 0.1 cm
Least Count = 0.1/10
= 0.01 cm
Main Scale Reading = 1.8 cm
Vernier Scale Reading = 4th div. coincides
= 4*L.C
= 4*0.01 cm
= 0.04 cm
i. Length = 1.8+0.04 cm
= 1.84 cm
ii. Zero Error = -0.02 cm
Total length = observed length - zero error
= 1.84-(-0.02) cm
= 1.84+0.02 cm
= 1.86 cm
Hope this helps.
