Question

A Physical quantity P is related to four observables a, b, c and d as
follows
P =ab?
vcd
The percentage errors of measurement in a, b, c and d are 196, 3%, 4%.
and 2% respectively. What is the percentage error in the quantity P​

Answer 1

Answer:

Solution :

Here,

<br> Maximum fractional error in P is given by <br>

<br>

<br> As the result (13%error) has two significant figures, therefore, if P turns out to be 3.763, the result would <br> be rounded off to 3.8.
