1.	A physical quantity is given is y = (a b^(3))/(c^(2)) . "If" Deltaa, Deltab, Deltac are absolute errors, the possible fractional error in y is .........
Answer» `(Deltay)/(y) =(DeltaaDeltab)/(2Deltac)` `(Deltay)/(y) = (Deltaa)/(a) +3 (DELTAB)/(B) + 2 (Deltac)/(C)` `(Deltay)/(y) = (Deltaa)/(a) + ((Deltab)/(a))^(3) + ((Deltac)/(c))^(2)` `(Deltay)/(y)= (Deltaa)/(a) + (Deltab)/(a) + (Deltac)/(c)` Solution :`(Deltay)/(y) = (Deltaa)/(a) + (Deltab)/(b) + 2 (Deltac)/(c)`
