Question

While measuring a wire a 5cm wire, a construction worker measured it 5.2 cm by mistake. What is the percent error?

Answer 1

4%

Explanation:

Actual length of wire = 5 cm

The measured length of wire = 5.2 cm

We need to find the percent error in the measurement of the length of wire. It can be calculated as follows :

`\%=\frac{\text{measured length-actiual length}}{\text{actual length}}* 100\\\\=(5.2-5)/(5)* 100\\\\=4\%`

So, the required percent error is 4%.
