The arms of a U-shaped tube have circular cross-sections. A lid that seals the wider arm requires a force of 45 N to remove it. The tube is filled with water and the narrow arm is fitted with a piston. If the maximum amount of force you can apply with your hand to the piston is 17 N, what is the minimum ratio of the diameters in the tube dbig/dnarrow in order for you to be able to pop out the lid?
