Question

A physical quantity S is related to three measurable
quantities a, b and c as S=a^3b^2/c
The errors in
the measurement of a, b and c are 1%, 2% and 3%
respectively. Find maximum possible percentage error
in the value of S.​

Answer 1

Answer:

10%

Explanation:

This is a problem of combination of errors.

When quantities are multiplied or divided, we simply add their percentage errors to get total percentage error.

And if quantities have power in the main equation, then multiply individual percentage errors with the corresponding power before adding to find total percentage error as it is done in the solved example below.
