A convex lens of focal length `20 cm` is placed co-axially with a convex mirror of radius of curvature `20 cm`. The two are kept `15 cm` apart from each other. A point object is placed `60 cm` in front of the convex lens. Find the position of the image formed by the combination.

Explanation

To solve the problem step by step, we will analyze the situation involving the convex lens and the convex mirror.

### Step 1: Identify the parameters
- Focal length of the convex lens, \( f_L = +20 \, \text{cm} \)
- Radius of curvature of the convex mirror, \( R = +20 \, \text{cm} \)
- Focal length of the convex mirror, \( f_M = \frac{R}{2} = +10 \, \text{cm} \)
- Distance between the lens and the mirror, \( d = 15 \, \text{cm} \)
- Object distance from the lens, \( u_L = -60 \, \text{cm} \) (negative as per the sign convention)
