In а cаr lift used in а service statiоn, cоmpressed air exerts a fоrce on a small piston that has a circular cross section and a radius of `r1`cm. This pressure is transmitted by a liquid to a piston that has a radius of `r2` cm. The force must the compressed air exert to lift a car weighing `F2` N equal to .............N. {Hint: Use Pascal law}
