A 5 cm tall object is placed on the principal axis of convex lens of focal length 50 cm at a distance of 40 cm from it. Find the nature, position and size of the image.

Explanation

To solve the problem, we will follow these steps:

### Step 1: Identify the Given Values
- Height of the object (h) = 5 cm
- Focal length of the convex lens (f) = +50 cm (positive because it's a convex lens)
- Object distance (u) = -40 cm (negative because it's on the same side as the incoming light)

### Step 2: Use the Lens Formula
