Question

THE vernier scale of callipers has 50 divisions if each coincide with 49 main scale divisions if each scale division is of 0.5 mm then the minimum inaccuracy in the measurement by callipers is​

Answer 1

Answer:

0.01 mm or 0.001 cm

Explanation:

least count is the minimum measurement which can be made from the particular instrument

formula of least count of verniar calliper is = value of 1 main scale division/number of divisions on vernier scale

SO,

value of 1 main scale division is 0.5mm and number of divisions on verniar scale are 50

least count = 0.5/50 = 0.01mm or 0.001 cm
