Question

derive an expression for error (absolute/relative) errors (b) when a quantity is product of two physical quantities ​

Answer 1

Answer:

In words, the absolute error is the magnitude of the difference between the exact value and the approximation. The relative error is the absolute error divided by the magnitude of the exact value. The percent error is the relative error expressed in terms of per 100.Relative error is a measure of the uncertainty of measurement compared to the size of the measurement. ... For example, an error of 1 cm would be a lot if the total length is 15 cm, but insignificant if the length was 5 km.
