The lens combination as shown in the figure, consists of two lenses, $L_1$ and $L_2$, of the focal lengths $+10$ cm and $-10$ cm, respectively. The position of the image formed is :

  1. A
    $20$ cm to the left of the concave lens
  2. B
    $60$ cm to the left of the concave lens
  3. C
    $30$ cm to the right of the concave lens
  4. D
    $60$ cm to the right of the concave lens

Correct answer · Option D

$60$ cm to the right of the concave lens

Explanation

Applying the lens formula successively for both lenses $L_1$ and $L_2$ with given object distance and focal lengths yields the final image position at $60$ cm to the right of the concave lens.
