An equiconvex lens 
of focal length 20 cm is cut into two equal parts and one part 
is silvered. Another concavo-convex lens 
(radii 10 cm and 20 cm, μ=1.5 ) is placed with its principle axis 2 mm above the principle axis of 
A point object ' O ' is placed at a distance of 80 cm from the lens on its principal axis as shown in figure. Find the position of final image.
- at a height of 6 cm directly above the object 'O'
- at a height of 4 mm directly above the abject 'O'
- at a distance 6ambelow the object 'O'
- at a distance of 4 an directly below the abject ' O '
The correct answer is: at a height of 4 mm directly above the abject 'O'
