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

Answer

To solve the problem, we need to understand how images are formed in a plane mirror. Here’s the step-by-step solution:

### Step 1: Understand the setup
We have an object placed in front of a plane mirror. The distance of the object from the mirror is given as 5 cm.

### Step 2: Determine the position of the image
In a plane mirror, the image formed is at 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 total distance between the object and the image
To find the total distance between the object and the image, we need to add the distance from the object to the mirror and the distance from the mirror to the image.

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

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

### Conclusion
The image formed by the object and the object itself will be 10 cm apart.
