Answer:
Given: u=−20 cm
f=R/2=15 cm
Size of image, h=5 cm
Let size of image be h ′
From mirror formula,
1/v +1/u = 1/f
1/v = 1/f – 1/u
1/v = 1/15 – 1/-20
v = 8. 57 cm
Image is virtual and erect and formed behind the mirror.
m = -v/u
m = h'/ho
hi/5= 8.57/20
= 0.428
h' = 0.428 x 5 = 2.14cm
Position of Image: Behind the mirror.
Nature of Image: Virtual and Erect.
Size of the Image: Diminished.
