When a converging lens is used in a camera (as in the first drawing), the film must be placed at a distance of 0.170 m from the lens to record an image of an object that is 4.70 m from the lens. The same lens is then used in a projector (as in the second drawing), with the screen 0.550 m from the lens. How far from the projector lens should the film be placed?
