1.	The correctness of equations can be checked using the principle of homogeneity.If percentage errors of measurement in velocity and mass are2%and4%respectively, tvhat.is the percentage error in kinetic energy?
Answer» Solution :KINETIC energy `K-1/2mv^2(DeltaK)/Kxx100=(DELTAM)/mxx100+2xx(DELTAV)/vxx100=4+2xx2=8%`
