A converging lens \(L_{1}\) has a focal length of \(12\) cm. An object is placed \(24\) cm to the left of \(L_{1}\). A second converging lens \(L_{2}\) of focal length \(6\) cm is positioned \(30\) cm to the right of \(L_{1}\). Determine (a) the position of the image formed by \(L_{1}\), (b) the nature and position of the final image formed by \(L_{2}\), and (c) the overall magnification of the two‑lens system. Give all distances measured from the respective lenses and give the magnification to two decimal places.

Answer Options

A. (a) +10 cm; (b) virtual image 5.00 cm to the left of L₂; (c) M ≈ 0.12
B. (a) -8 cm; (b) real image 3.50 cm to the right of L₂; (c) M ≈ 0.05
