Two converging lenses, 1 and 2, are positioned facing each other, with lens 1 on the left. The focal length of lens 1 is \(100 \mathrm{~mm}\), that of lens 2 is \(180 \mathrm{~mm}\), and the two lenses are \(150 \mathrm{~mm}\) apart. If an object is \(50 \mathrm{~mm}\) to the left of lens 1,

(a) at what distance from lens 2 should a screen be placed if the object's image is to be focused on the screen?

(b) What is the overall magnification of the image?

(c) Is the image upright or inverted?
