1.	The Vernier scale of travelling microscope has 50 divisions. If each main scale division is 0.5 mm, calculate the minimum inaccuracy in the measurement of distance.
Answer» Given: 50 VSD = 49 MSD (VSD-Vernier Scale division, MSD-Main scale divisions) ⇒ 1 MSD = \(\frac{50}{49}VSD\) 1 VSD = \(\frac{49}{50}MSD\) Inaccuracy (minimum) = \(\frac{1}{50}\times0.5mm\) =0.01 mm

The Vernier scale of travelling microscope has 50 divisions. If each main scale division is 0.5 mm, calculate the minimum inaccuracy in the measurement of distance.

Answer»

Given:

50 VSD = 49 MSD

(VSD-Vernier Scale division, MSD-Main scale divisions)

⇒ 1 MSD = \(\frac{50}{49}VSD\)

1 VSD = \(\frac{49}{50}MSD\)

Inaccuracy (minimum) = \(\frac{1}{50}\times0.5mm\)

=0.01 mm
