The magnification of an object 2cm tall when placed 10cm in front of a plane mirror is

Answer Details

When an object is placed in front of a plane mirror, its image appears to be behind the mirror, at the same distance from the mirror as the object is in front of it. The image appears to be a virtual image that is the same size as the object, but reversed from left to right.
In this case, the object is 2cm tall and is placed 10cm in front of the mirror. The image will appear to be 10cm behind the mirror, which is the same distance as the object is in front of the mirror. The image will also be the same size as the object, which is 2cm tall.
To find the magnification, we need to divide the height of the image by the height of the object:
Magnification = height of image / height of object
In this case, the height of the image is 2cm and the height of the object is also 2cm, so:
Magnification = 2cm / 2cm = 1.0
Therefore, the magnification of the object when placed 10cm in front of a plane mirror is 1.0. This means that the image appears to be the same size as the object.
