would it be form its image?​

Answer 1

Answer:

Explanation:

The object would be 15cm far away from its image if it is placed at a distance of 7.5cm from the plane mirror. The object is  7.5cm from the mirror, then the image of the object is 7.5cm on the other side of the mirror. Hence, the image is a total of 15cm from object (7.5cm to the mirror+ 7.5cm to the image)

Hope it helps

Answer 2

Answer:

Answer. we know that, the distance between the object and the reflected image from the mirror is same. So if an object is placed at a distance of 7.5cm from a plane mirror its image will form (7.5+7.5=15) 15cm far.
