Answer 2

Answer:

Explanation:   size of object =5cm

                        u=20cm

                        f=r/2=30/2=15cm

1/F=1/V+1/U

1/15=1/15+1/20

1/V=1/15-1/20

finally v=60

IT MEANS A VIRTUAL AND ERECT IMAGE FORMED BEHIND THE MIRROR AND SIZE OF IMAGE

m=-v/u=1/size of object

1=(-v*object/u)

= -60*5/20= -15cm

SO YOUR MAGNIFICATION (M= - 15 CM )
