The near vision of an average person is `25 cm`. To view an object with an angular magnification of `10`, what should be the power of the microscope ?

Explanation

To find the power of the microscope needed to achieve an angular magnification of 10, we can follow these steps:

### Step 1: Understand the relationship between angular magnification and focal length
The angular magnification (m) of a microscope is given by the formula:
\[ m = \frac{d}{f} \]
where:
- \( m \) = angular magnification
- \( d \) = least distance of distinct vision (near vision), which is 25 cm for an average person
