The diameter of a wire as measured by a ...

The diameter of a wire as measured by a screw gauge was found to be `1.002cm, 1.000cm` and `1.006cm`. The absoulue error in the first reading.

A

`0.001cm`

B

`0.04cm`

C

`0.006m`

D

`0.003cm`

Text Solution

Verified by Experts

The correct Answer is:
A
`a_("mean") = (a_(1) + a_(2) + a_(3))/(3), Delta a_(3) = |a_("mean") - a_(3)|`
