An object of height 20 cm is kept at a distance of 48 cm in front of a concave mirror of focal length 12 cm. If the mirror forms a virtual, diminished image of the object then calculate the distance of the image from the mirror.

Explanation

To solve the problem step by step, we will use the mirror formula and the given data.

### Step 1: Identify the given values
- Height of the object (h) = 20 cm
- Distance of the object from the mirror (u) = -48 cm (the negative sign indicates that the object is in front of the mirror)
- Focal length of the concave mirror (f) = -12 cm (the negative sign indicates that it is a concave mirror)

### Step 2: Write down the mirror formula
