An object of height 2 cm is placed on a principal axis at a distance of 10 cm from the pole of concave mirror. The image height is 5 cm. Find the image distance and the focal length of the concave mirror if the image is real and inverted.

Explanation

To solve the problem step by step, we will use the concepts of concave mirrors, magnification, and the mirror formula.

### Step 1: Identify the Given Values
- Height of the object (h₀) = 2 cm
- Distance of the object from the mirror (u) = -10 cm (negative as per sign convention)
- Height of the image (hᵢ) = -5 cm (negative as the image is inverted)

### Step 2: Use the Magnification Formula
