A physical quantity A is dependent on other four physical quantities p,q,r and s as given by `A=(sqrt(pq))/(r^(2)s^(3))`. The percentage error of measurement in p,q,r and s are 1%,3%,0.5% and 0.33% respectively, then the maximum percentage error in A is

A

0.02

B

0

C

0.04

D

0.03

Text Solution

Verified by Experts

The correct Answer is:
C
`%` error in `A = 1/2` (`%` error in `p`) `+ 1/2` (`%` error in `q`)
`+2`(`%` error in `r`) `+3`(`%` error in `s`).
