A convex lens of focal length 10 cm. is used as a magnifying lens.
What will be the magnification?

Explanation

To find the magnification produced by a convex lens of focal length 10 cm when used as a magnifying lens, we can use the formulas for magnification at the near point and the far point.

### Step-by-Step Solution:

1. **Identify the Focal Length (f)**:
The focal length of the convex lens is given as \( f = 10 \, \text{cm} \).

2. **Understand the Near Point (d)**:
