Question

if the measured values of datermine by using micrometre screw are-2.241cm,2.246cm,2.248cm,2.240cm,2.241cm calculated relative error & % error in the measurement​

Answer 1

relative error=0. 0067

% error =. 67%

Explanation:

Mean value = (2.241 + 2.246 + 2.248 + 2.240 + 2.241) /5 = 2.243

Absolute error =|mean value-measured value|

=0.002 +0.003+0.005+0.003+0.002=0.015

Relative error=absolute error÷mean value

=0.015÷2.243=0.0067

%error =relative error x 100=0.0067 x 100= 0.67%
