Answer 2

Answer:

nature = upright erect diminished

position = 15/16 from pole

size of image = -75/16

Explanation:

given height = 5 cm

distance (u) = 1 cm

focal length = 15 cm

∵ 1/f = -1/u+1/v

1/15 = 1 + 1/v

16/15 = 1/v ∴ v = -15/16    

∵m=-v/u = -hi/ho

m = 15/16

-hi/5=15/16

hi = -75/16
