we are given that object distance (u)=-15
focal length (F)=-10
therefore from the formula 1/F=1/u+1/v
we get 1/v= -1/10+1/15
1/v=-1/30
therefore v=- 30
focal length (F)=-10
therefore from the formula 1/F=1/u+1/v
we get 1/v= -1/10+1/15
1/v=-1/30
therefore v=- 30

given- h=2cm u=-15cm and f=-10cm.
to find:- v=?
F.A:- 1/U+1/V=1/F
1/-15+1/V=1/-10
1/V=1/-10+1/15
1/V=-3+2/30
1/V=-1/30
V=-30
