Answer 2

To find:  Relative Error in the measurement

Given:

The length of rod = 2.546 cm

Explanation:

Relative error : Expresses how large the absolute error is compared with the total size of the object you are measuring. Relative error is expressed as a fraction or is multiplied by 100 and expressed as a percent.

Formula for finding Relative error = (Absolute error / “True” value) * 100%.

                                                       = (2.445/2.546) * 100%.

                                                        = 0.96 * 100%.  = 96 %

Relative error is the measure of accuracy ($R_{E}$)
