In a vernier callipers, 50 vernier scale divisions are equal to 48 main scale divisions. If one main scale division , then the least count of the vernier callipers is mm.
Options
- A0.005
- B0.05
- C0.002
- D0.02
Correct answer
C. 0.002
Step-by-step solution
Given: 50 vernier divisions = 48 main divisions and 1 main division = 0.05 mm
50 vernier divisions = 48 × 0.05 = 2.4 mm
1 vernier division = 2.4/50 = 0.048 mm
Least count = 1 main division - 1 vernier division = 0.05 - 0.048 = 0.002 mm
50 vernier divisions = 48 × 0.05 = 2.4 mm
1 vernier division = 2.4/50 = 0.048 mm
Least count = 1 main division - 1 vernier division = 0.05 - 0.048 = 0.002 mm
