95 through 100 GO 95, 96, 99 Three-lens systems . In Fig. 34-49, stick figure O (the object) stands on the common central axis of three thin, symmetric lenses, which are mounted in the boxed regions. Lens 1 is mounted within the boxed region closest to O , which is at object distance p 1 . Lens 2 is mounted within the middle boxed region, at distance d 12 from lens 1. Lens 3 is mounted in the farthest boxed region, at distance d 23 from lens 2. Each problem in Table 34-10 refers to a different combination of lenses and different values for distances, which are given in centimeters. The type of lens is indicated by C for converging and D for diverging; the number after C or D is the distance between a lens and either of the focal points (the proper sign of the focal distance is not indicated). Find (a) the image distance i 3 for the (final) image produced by lens 3 (the final image produced by the system) and (b) the overall lateral magnification M for the system, including signs. Also, determine whether the final image is (c) real (R) or virtual (V), (d) inverted (I) from object O or noninverted (NI), and (e) on the same side of lens 3 as object O or on the opposite side. p 1 Lens 1 d 12 Lens 2 d 23 Lens 3 (a) i 3 (b) M (c) R/V (d) I/NI (e) Side 95 +12 C, 8.0 28 C, 6.0 8.0 C, 6.0 Figure 34-49 Problems 95 through 100.

The figure shows four orientations of an electric di-
pole in an external electric field. Rank the orienta-
tions according to (a) the magnitude of the torque
on the dipole and (b) the potential energy of the di-
pole, greatest first.
