Question

If the formula for a physical quantity is
ab
X= and if the percentage error
cd2
in the measurements of a, b, c and d
are 2%, 3%, 3% and 4% respectively.
Calculate percentage error in X



GIVE FULL EXPLANATION ​

Answer 1

$\large\rm { X = \frac {A²B³}{C \sqrt{D}} = \frac {A²B³}{CD^{1/2}} }$

so the answer is 19.5 %

But we can't predict that percentage is positive or negative.

Answer 2

Answer:

\large\rm { X = \frac {A²B³}{C \sqrt{D}} = \frac {A²B³}{CD^{1/2}} }X=

C

D

A²B³

=

CD

1/2

A²B³

so the answer is 19.5 %

But we can't predict that percentage is positive or negative.
