Question

Question is given below...

Answer 1

A physical quantity x is calculated from \[x=(ab ^{2})/\sqrt{c}\]If the % error in measuring a,b,c are 4,2,3 respectively then the % error in measuring x is:
a)4%
b)6%
c)9%
d)9.5%

Answer 2

d

Answer 3

I don't want direct answer.. tell me how do you get it?

Answer 4

c i guess (4*2^2)/sqrt(3)

Answer 5

if \[x=\frac{a^nb^m}{c^q}\]

then the % error in x is \[\frac{\Delta x}{x}\times100=n\times\frac{\Delta a}{a}\times100+m\times\frac{\Delta b}{b}\times100+q\times\frac{\Delta c}{c}\times100\]

Answer 6

now you can do it.
