Question

call measuring a wire of length 5 cm a construction worker measures 5.2 CM by mistake find the percentage error in the measuring wire​

Answer 1

4%

Explanation:

`Percentage\:Error=(Error)/(Correct\:Value)*100\%`

The exact or correct value is 5cm

The inaccurate value is 5.2cm

The error value is |5.2-5.0|=0.2

This implies that:

`Percentage\:Error=(0.2)/(5)*100\%`

This simplifies to:

`Percentage\:Error=0.04*100\%`

`Percentage\:Error=4\%`

Hence the percentage error is 4%
