One side of radius of curvature R2=120cm of a convexo-convex lens of material of refractive index n=1.5 and focal ength f1=40 cm is silvered. It is placed on a horizontal surface with the silvered surface in contact with it.Another convex lens of focal length f2=20cm is fixed coaxially d=10cm above 1st lens.A point object on axis give rise to an image coincident with it.Find the height of the object above the upper lens
