The two surfaces of a biconvex lens has same radii of curvatures . This lens is made of glass of refractive index 1.5 and has a focal length of 10 cm in air. The lens is cut into two equal halves along a plane perpendicular to its principal axis to yield two plane - convex lenses. The two pieces are glued such that the convex surfaces touch each other. If this combination lens is immersed in water (refractive index = 4/3 ), its focal length (in cm ) is
