Answer:
The distance of the image from the mirror is 30 cm.
Explanation:
The magnification in a mirror is −v/u, where v and u
are the distances of the image and the object from the mirror respectively.
It is given that the image is real and three times the size of the object.
⇒The distance of the image from the mirror is three times the distance of the object and the image is on the same side of the mirror as the object.
The distance of the object from the mirror is 10 cm.
=>
The distance of the image from the mirror is 30 cm.
