An object 2.5 cm high is placed in front of a convex lens of focal length 30 cm. If the height of image formed is 5 cm, find the distance between the object and the image?

Explanation

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

### Step 1: Understand the given data
- Height of the object (h_o) = 2.5 cm
- Height of the image (h_i) = 5 cm
- Focal length of the convex lens (f) = 30 cm

### Step 2: Calculate the magnification (m)
