If an object is placed at a distance of 5 cm from a plane mirror, how far would it be from its image ?

Answer

To solve the question, "If an object is placed at a distance of 5 cm from a plane mirror, how far would it be from its image?", we can follow these steps:

### Step 1: Understand the setup
We have a plane mirror and an object placed 5 cm away from it.

### Step 2: Determine the position of the image
In a plane mirror, the image formed is virtual and appears to be the same distance behind the mirror as the object is in front of it. Therefore, if the object is 5 cm away from the mirror, the image will also be 5 cm behind the mirror.

### Step 3: Calculate the distance between the object and the image
To find the distance between the object and its image, we need to add the distance of the object from the mirror and the distance of the image from the mirror.

- Distance of the object from the mirror = 5 cm
- Distance of the image from the mirror = 5 cm

So, the total distance between the object and the image is:
\[ \text{Distance between object and image} = \text{Distance of object from mirror} + \text{Distance of image from mirror} \]
\[ = 5 \, \text{cm} + 5 \, \text{cm} = 10 \, \text{cm} \]

### Conclusion
The distance between the object and its image is 10 cm.
