The pressure of a gas in a container is estimated to be the force exerted per cross-sectional area. If a factor F=(20.0+/-0.5)N.acts on a rectangular cross-section of the container with dimensions x=(5.0+/-0.5). Calculate fractional change in pressure and percentage error in pressure of gas
Total error is (0.54)^1/2=0.73
0.73/20×100=3.65%
