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

Answer:

4%

Step-by-step 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 :

$\%=\dfrac{\text{measured length-actiual length}}{\text{actual length}}\times 100\\\\=\dfrac{5.2-5}{5}\times 100\\\\=4\%$

So, the required percent error is 4%.
