1.	A physical quantity X is related to three observable a,b and c as X=(b^(2)sqrt(a))/c. The errors of measuremnts in a,b and c are 4%, 3% and 2% respectively. What is the percentage error in the quality X?
Answer» SOLUTION :`R=V//I=11.1//5.5=2.02Omega, DELTAR//R=DeltaV//V+DeltaI//I=0.1//11.1+0.5//5.5=0.099` `DeltaR=(0.099xx11.1)//5.5=0.199=0.2Omega`.RESISTANCE `=(2.02+-0.2)OMEGA`
