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

Answer:

4%

Step-by-step explanation:

$Percentage\:Error=\frac{Error}{Correct\:Value}*100\%$

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:

$Percentage\:Error=\frac{0.2}{5}*100\%$

This simplifies to:

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

$Percentage\:Error=4\%$

Hence the percentage error is 4%
