List-I (Specifications) List-II (Least Count) A. 10 main scale divisions per cm, 10 VSD = 9 MSD I. 0.05 mm B. 20 main scale divisions per cm, 20 VSD = 19 MSD II. 0.02 mm C. 20 main scale divisions per cm, 25 VSD = 24 MSD III. 0.025 mm D. 10 main scale divisions per cm, 20 VSD = 19 MSD IV. 0.1 mm Choose the co

Options

  1. AA-IV, B-II, C-III, D-I
  2. BA-I, B-III, C-II, D-IV
  3. CA-IV, B-III, C-II, D-I
  4. DA-I, B-II, C-III, D-IV

Correct answer

C. A-IV, B-III, C-II, D-I

Step-by-step solution

For a vernier calliper where n VSD = (n-1) MSD, the Least Count (LC) is given by 1 n MSD . A. 10 divisions/cm 1 MSD = 1 10 cm = 1 mm . LC = 1 mm 10 = 0.1 mm . (Matches IV) B. 20 divisions/cm 1 MSD = 1 20 cm = 0.5 mm . LC = 0.5 mm 20 = 0.025 mm . (Matches III) C. 20 divisions/cm 1 MSD = 1 20 cm = 0.5 mm . LC = 0.5 mm 25 = 0.02 mm . (Matches II) D. 10 divisions/cm 1 MSD = 1 10 cm = 1 mm . LC = 1 mm 20 = 0.05 mm . (Matches I) Therefore, the correct matching is A-IV, B-III, C-II, D-I. Answer: A-IV, B-III, C-II, D-I
