An object is placed at a distance of 12 cm from a convex lens of focal length 8 cm. Find :
the position of the image

Explanation

To find the position of the image formed by a convex lens, we can use the lens formula:

\[ \frac{1}{f} = \frac{1}{v} - \frac{1}{u} \]

where:
- \( f \) is the focal length of the lens,
