If the object is 5 cm away from the plane mirror, the image formed by it and the object will be ............ cm apart.

Options

A. 2.5
B. 5
C. 10
D. 15

Explanation

To solve the problem, we need to understand how images are formed by plane mirrors.

### Step-by-Step Solution:

1. **Understanding the Plane Mirror**: A plane mirror forms an image that is virtual, upright, and of the same size as the object. The distance of the image from the mirror is equal to the distance of the object from the mirror.

2. **Distance of the Object from the Mirror**: According to the question, the object is 5 cm away from the plane mirror.

3. **Distance of the Image from the Mirror**: Since the image distance is equal to the object distance in the case of a plane mirror, the image will also be 5 cm away from the mirror.

4. **Calculating the Distance Between the Object and the Image**:
- The total distance between the object and the image can be calculated by adding the distance of the object from the mirror and the distance of the image from the mirror.
- Therefore, the distance between the object and the image = Distance of the object from the mirror + Distance of the image from the mirror = 5 cm + 5 cm = 10 cm.

5. **Conclusion**: The object and the image will be 10 cm apart.

### Final Answer:
The object and the image will be **10 cm apart**.
