Convex lens of focal length f is split into two half from its principal axis the separation between two lens is 20 cm the separation between nearest lens and object is 30 cm as shown in the figure. If image by nearest lens is formed at infinity. The image of the object formed by second lens from its optical center is
Answer & explanation
Correct answer: option 1
If object is at 30 cm then image is formed at infinity
∴ f = 30 cm
$\frac{1}{V}-\frac{1}{-50}=\frac{1}{30}$ V = 75 cm
