A concave mirror is used for image formation for different positions of an. object. ... Nature of the image.

Answer 2

Answer:Position of image --> 30 cm

Size of the image--> enlarged

Nature of image----> real and inverted

Step-by-step explanation:

Given

u=-10 cm

f=-15 cm

mirror formula --->1/f=1/v+1/u

-1/15=1/v-1/10

-1/15+1/10=1/v

-2/30+3/30=1/v

1/30=1/v

v=30cm

Now For SIZE

m=Hi/H=-v/u

m=-30/-10

m=3
