Arubber ducky is placed 20 cm from a thin convex lens with a focal length of 15 cm. which statement correctly describes the nature and position of the image formed of the rubber ducky? a) real and upright on the side of the lens opposite the rubber ducky. b) real and inverted on the side of the lens opposite the rubber ducky. c) imaginary and upright on the side of the lens opposite the rubber ducky. d) imaginary and inverted on the same side of the lens as the rubber ducky.

An charge with mass m and charge q is emitted from the origin, (x,y)=(0,0). a large, flat screen is located at x=l. there is a target on the screen at y position y(h), where y(h) > 0. in this problem, you will examine two different ways that the charge might hit the target. ignore gravity in this problem. 1.assume that the charge is emitted with velocity v(0) in the positive x direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive y direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l. 2.now assume that the charge is emitted with velocity v(0) in the positive y direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive x direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l.
