Compressed air in a vertical cylinder with a piston of radius 0.30m0.30m is used to lift a crate. The minimum pressure of the air in the cylinder needed for the piston to lift the crate is 1.61×105N/m21.61×105N/m2, and the pressure in the room outside the piston is 1.01×105N/m21.01×105N/m2. If the mass of the piston is negligible, the weight of the crate is most nearly
