A small object is placed on the axis of a convex lens of focal length 0.2 m at a distance of 0.5 m from it. Find the position and linear magnification of the image.

Explanation

To solve the problem step by step, we will use the lens formula and the magnification formula for a convex lens.

### Step 1: Identify the given values
- Focal length of the convex lens (f) = 0.2 m (positive for convex lens)
- Object distance (u) = -0.5 m (negative as per sign convention)

### Step 2: Use the lens formula
The lens formula is given by:
