An object 2 cm tall is placed on the axis of a convex lens of focal length 5 cm at a distance of 10 m from the optical center of the lens. Find the nature, position and size of the image formed. Which case of image formation three times. Find the distance of the lens from the filament and the focal length of the lens.

Explanation

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

### Step 1: Identify the given data
- Height of the object (h_o) = 2 cm
- Focal length of the convex lens (f) = 5 cm
- Distance of the object from the lens (u) = -1000 cm (since the object is placed on the same side as the incoming light, we take it as negative)

### Step 2: Use the lens formula
