till now no one?????
A thin convex lens whose focal length in air is known to be 30cm is cut into two parts by a transverse plane parallel to principal axis and 0.5cm above the principal axis. They are placed on the xaxis a shown in the figure.A point object is placed on the origin of the coordinate system.Find the coordinates of the final image formed due to the rays which get refracted by both the parts of the lens (assuming paraxial ray approximations to be valid)

Oh yeah, i made big mistakes :P
Akshay, which part of the lens is placed where....Is it given ?
1/v  1/(45)=1/30
therefore v will be 90.....
now this will act as an object for the second lens
1/v  1/15=1/(30)
u will get v as 30
therefore the image will be formed at (90+30)=120.....
(i think this is the answer)
nopes !!
i hav mentioned all the data above which is given in the question .
nothing else is given... bro.
I was going in the same way as urs ......
but buddy answer given is that final image is formed at (120cm, 1cm)
The 1 can be calculated by finding out the magnifications on consecutive refractions0.50.5
