One half of a convex lens of focal length 10 cm is covered with a black paper. Can such
a lens produce an image of a complete object placed at a distance of 30 cm from the
lens? Draw a ray diagram to justify your answer. A 4 can tall object is placed
perpendicular to the perpendicular to the principal axis of a convex lens of focal length 20 cm. The distince
of the object from the less is 15 cm. Find nature, position and size of the image.

Explanation

### Step-by-Step Solution

#### Part 1: Image Formation with Half of the Convex Lens Covered

1. **Identify Given Data**:
- Focal length of the lens (f) = 10 cm
- Object distance (u) = -30 cm (negative as per sign convention)
