The least count of verniercallipers is 0.1 mm. The main scale reading before the zero of the vernier scale in 10 and the zeroth division of vernier scale coincides with the main scale division. Given that each main scale division is 1 mm. The measured value should expressed as –
A
0.01 cm
B
0.001 cm
C
0.1 cm
D
1.00 cm
Answer
1.00 cm
Explanation
Solution
Least count = 0.1 mm
Main scale reading = 10 × 1 mm = 10 mm
Vernier scale reading = 0 × 0.1 = 0
So, Reading = 10mm + 0 = 10 mm = 1.00 cm
