                  The vernier scale of a traveling microscope has 50 divisions which coincide with 49 main scale divisions. If each main scale division is 0.5 mm, calculate the minimum inaccuracy in the measurement of distance.                

Answer:

                  Least count of microscope                 \[=\left( 1-\frac{49}{50} \right)=\text{MSD}=\frac{1}{50}\times 0.5\,\,mm\]                 \[=0.01\,\,m\]                 = Minimum inaccuracy in the measurement.
