Solution:
If the magnification of a body of size 1 m is +2, then the size of the image is 2 m.
Given,
Size of body, h1= 1 m
Magnification, m = 2
The magnification produced by the mirror is defined as the ratio of the height of the image to the height of the object.
We know that,
m=h2h1 ….(1)
Where h2 is the size of the image and h1is the size of the object.
Substituting the given value in equation (1) we get
2=h21
h2=2×1
h2=2 m
