When the jaw of verniercallipers are in contact the zero of the vernier scale lies left of the first division of the main scale and fourth division coincides with main scale. The minimum reading which this instrument can give is 0.01 cm. A cylinder's diameter is measured by this then it reads 1 cm on the main scale and 5 th division of the vernier coincides with the 15 th division of the main scale. The radius is -
Text Solution
Verified by ExpertsThe correct answer is:
D
LC = 0.1 mm
MSR = 1 cm = 10 mm
VCR = 5 × 0.1 = 0.5 cm
λ = 4 × 0.1 = 0.4 cm
2r = 10 + 0.5 – 0.4 = 10.1 mm
r = 5.05 mm
