Question

a physical quantity epsilon is calculated by using the formula epsilon = xy2÷10z1/3 where x y and z are experimentally measured quantities if the fractional % error in the measurements of x y and z are 2% 1% 3% respectively then the fractional % error in epsilon will be

Answer 1

Answer:

Given that,

%in x=2%

%in y=1%

And % in z=3%

Now.

By the question

Xy^2

- - - - - - - - -

10z^1/3

So

= %in x +1/2% in y+1/3%in z

= 2+1/2+1/3*3

=2+1/2+1

= 3.5%

That is the error in epsiol
