Question

A concave mirror produces three times magnified (enlarged) real image
of an object placed at 10 cm in front of it. Where is the image located?
​

Answer 1

Step-by-step explanation:

magnification(m)=-3(as image is real)

object distance (u)=-10cm

image distance (v)=?

we know that m=-v/u

-3=-v/-10

-3=v/10

v=-3*10

v=-30cm

thus the image is 30 cm away from the concave mirror

hope its help!!

plzz follow me

Answer 2

Step-by-step explanation:

Given magnification m=3

and object distance u=10 cm and we know,

Magnification m=

u

−v

−v=3×−10

v=30 cm

Thus the image is formed at distance of 30 cm.
