Question

An images formed 5 cm behind a

convex mirror of focal length 10 cm.

At what distance is the object placed

from the mirror
​

Answer 1

Answer: mark as brainliest if it helps.

Object distance U = -5 cm(to the left of mirror)

Image distance V = ?

Focal length f = 10 cm(convex mirror)

By using the mirror formula we have

1/V + 1 / U = 1/f

1/V + 1/-5 = 1/10

1 / V = 1/10 + 1/5

1/V = 3/10 or V = 10/3

V = +3.33cm

Position of the image is at a distance of 3.33 cm from the convex mirror on its right side(behind the mirror). Since the image is formed behind the convex mirror, therefore the nature of image is virtual and erect.

Magnification m = - V/U

So m = - (3.33)/-5

m = +0.66
