Question

Find the zero error in the following figures if the least count of the screw

gauge is 0.01mm​

Answer 1

Answer:

Answer

Correct option is

A

−0.02 mm

The screw gauge is at 98 at its mean position

i.e. (100−98)=2 division behind.

we know that, least count of screw gauge is

=0.01 mm

If is behind the mean position

:. negative error

and equal t0=

−2× Least count

=−0.02 mm
