Answer:
The relative error is defined as the ratio of the absolute error of the measurement to the actual measurement. If the true measurement of the object is not known, then the relative error can be found using the measured value. The relative error gives an indication of how good the measurement is relative to the size of the object being measured.
Relative error = (x0-x)/x = (Δx)/x
Where,
- x = Actual value of a quantity
- x0 = Measured value of the quantity
- Δx Absolute error
It is two times the error in A. If two quantities are multiplied or divided the relative error in the result is the sum of the relative errors in the multipliers.
