A converging lens L\(_1\) has focal length \(f_1 = 12\) cm. An object is placed 30 cm to the left of L\(_1\). A second converging lens L\(_2\) with focal length \(f_2 = 10\) cm is placed to the right of L\(_1\). The final image formed by L\(_2\) is located 8 cm to the right of L\(_2\). Determine (a) the distance between the two lenses, and (b) the overall linear magnification of the system (ratio of image height to object height).

Answer Options

A. Distance between lenses ≈ 48.6 cm; overall magnification = 0.057
B. Distance between lenses ≈ 42.0 cm; overall magnification = -0.045
Correct Answer C. Distance between lenses ≈ 48.6 cm; overall magnification = -0.057
D. Distance between lenses ≈ 55.2 cm; overall magnification = -0.062
Correct Answer
C
Correct Option:
Distance between lenses ≈ 48.6 cm; overall magnification = -0.057
