  The least counts of two instruments are LC₁ = 0.02 mm and LC₂ = 0.005 mm. Which statements are correct?

  Select all that apply

  • Option A

    Instrument 2 has four times finer resolution than instrument 1.

  • Option B

    For a 1.00 mm measurement, one-LC fractional uncertainty is 2% for instrument 1.

  • Option C

    For a 1.00 mm measurement, one-LC fractional uncertainty is 0.5% for instrument 2.

  • Option D

    A smaller least count always guarantees absence of systematic error.

  A vernier calipers has 20 VSD = 18 MSD and 1 MSD = 1 mm. Which statements are correct?

  Select all that apply

  • Option A

    Least count = 0.10 mm

  • Option B

    Least count = 0.05 mm

  • Option C

    If the 7th vernier division coincides, the vernier contribution is 0.70 mm

  • Option D

    For the same MSD, a 20 VSD = 19 MSD vernier has better resolution
