A body of length 6 cm is placed 10cm from a concave mirror of focal length 20cm. Find the position, size, and nature of the image.

Explanation

To solve the problem, we will follow these steps:

### Step 1: Identify the given values

- Object distance (u) = -10 cm (negative because the object is in front of the mirror)
- Focal length (f) = -20 cm (negative for concave mirrors)

### Step 2: Use the mirror formula
