Q. 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:-

Here given Magnification m = 3, Object-distance u = 10 cm

v
Magnification m =
Real image
u
v
− 3 =
u
3 u = v
v = 3u = 3 × − 10 cm = − 30 cm

The image will be formed at a distance of 30 cm in front of convex mirror from its the pole
