Question

a microscope is provided with a main scale graduated with 20 division in 1 cm and a venier scale with50 division on it of length same as of 49 division of main scale. find the least count of the microscope.​

Answer 1

Hey there!

Given,

20 divisions = 1 cm

then, 1 division = 1/20 = 0.05 cm

Now,

Least Count = Value of 1 main scale division / Total no. of divisions

                    = (1/20) / 50

                    = 1/1000

                    = 0.001 cm

Hope It Helps You!

Answer 2

Answer:

Thus the L.C. of the microscope will be 0.001cm
