Question

Diameter of the solid cylinder is measured by Vernier caliper is 2.43 cm. If the L.C. of Vernier caliper is 0.01 cm. Calculate percentage error.
​

Answer 1

Answer:

Main scale can measure 5.10 and 5.15

∴ Main scale division (s) =0.05cm

Also, vernier scale division (v) =

50

2.45

=

100

4.9

=0.049cm/div

Thus, least count =0.05−0.049=0.001cm

Diameter =5.10+24×0.001

=5.124cm
