1.	A force F is applied on a square plate of side L. If percentage erroe in determine of L is 2% and that in F 4% the permissible error in pressure is…..
Answer» 0.02 0.04 0.06 0.08 Solution :Pressure P=`(F)/(A)=(F)/(L^(2))` `(DELTAP)/(P)XX100=((DeltaF)/(F)xx100)+2((DELTAL)/(L)xx100)=4%+2(2%)` `(DeltaP)/(P)xx100=8%`
