Question

Student measured the length of a metal piece and found it to be 23.1 cm. The actual length of the piece of metal is 22.0 cm.

Answer the following questions:
a) Calculate the error in the length of metal.
b) Calculate the percentage error in the length.

Answer 1

1. 3.1 cm
2. 14.1%

Step-by-step explanation:

L.error = student's measurement - actual length

L.error = 23.1-20.0

= 3.1

the percentage is 3.1/22*100=14.1%
