A convex lens of focal length `20 cm` and a convex mirror of focal length `10 cm` are placed co-axially `50 cm` apart from each other. An incident beam parallel to its principal axis is incideent on the convex lens. Locate the position of final image formed due to the combination.

Explanation

To solve the problem step-by-step, we will follow these steps:

### Step 1: Identify the components and their properties
- We have a convex lens with a focal length (f_lens) of +20 cm.
- We have a convex mirror with a focal length (f_mirror) of +10 cm.
- The distance between the lens and the mirror is 50 cm.

### Step 2: Determine the image formed by the convex lens
