Question

an object is placed at a distance 3f/2 from a concave mirror of focal length 'f' . find the position of image in terms of f. what is the magnification and nature of image formed

Answer 1

Given:
u=-3f/2 after sign conventions
v=?
f=-f
by mirror formula:
1/f=1/v+1/u
1/v=1/f-1/u
=-1/f-2/3f
=(-3+2)/3f
=-1/3f
v=-3f image is beyond C
thus, m=-v/u=+3f/(-3f/2)=-2
m=-2
image is real, inverted and magnified

Answer 2
