Answer:
size ⇒ 2 cm
nature ⇒ real and inverted
position ⇒ the image is formed at a distance of 30cm towards the left side of the pole
Explanation:
u = -15 cm, f = -10 cm and h = 1 cm
from the mirror formula we get 1/f = 1/v + 1/u
1/v = (1/-10) - (1/-15) ⇒ v = -30
m = h'/h = -u/v ⇒ h' = -1×-30/-15 ⇒ h' = -2
