There is a point object and a plane mirror. If the mirror is moved by 10cm away from the object, find the distance which the image will move.

Explanation

To solve the problem of how far the image moves when the plane mirror is moved 10 cm away from a point object, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Initial Setup**:
- Let the initial distance between the point object and the plane mirror be \( x \) cm.
- The image formed by a plane mirror is located at the same distance behind the mirror as the object is in front of it. Therefore, the initial position of the image is also at \( x \) cm from the mirror.
