(II) Two lenses, one converging with focal length 20.0 $\mathrm{cm}$ and one diverging with focal length $-10.0 \mathrm{cm},$ are placed 25.0 $\mathrm{cm}$ apart. An object is placed 60.0 $\mathrm{cm}$ in front of the converging lens. Determine $(a)$ the position and $(b)$ the magnification of the final image formed. (c) Sketch a ray diagram for this system.
