A physical quantity X is connected from ...

A physical quantity X is connected from X = `ab^(2) //c`. Calculate percentage error in X, when % error in a,b,c are 4,2 and 3 respectively.

Text Solution

Verified by Experts

`n= (ab^(2))/( c)`
The percentage error in n is
`(Deltanxx100)/(n)=(Deltaaxx100)/(a)+(2Deltabxx100)/(b)+(Deltacxx100)/(c)`
`:. (Deltanxx100)/(n)=4%+4%+3% =11%`
