Answer 2

HEY THERE ↓↓↓

size of the object O = 5cm, u =20cm, f=r/2=30/2=15cm

hence by mirror formula,

1/f=1/v+1/u

1/15=1/v+1/20

1/v=1/15 -1/20

hence, v=60 cm

it means a virtual and erect image is formed behind the mirror and size of the image,

m= -V/U=I/O

I =( -V/U)× O

= -60×5/20

=-15 CM
