If the optic axis of convex and concave lenses are separated by a distance `5 mm` as shown in the figure. Find the coordinate of the final image formed by the combination if parallel beam of light is incident on lens. Origin is at the optical centre of convex lens

A convex lens and a concave lens are kept separated by a distance d. If they are placed in close contact, the focal length of the combination

A point ofject 'O' lies in front of the lens as shown in figure. Find the final position of image formed by the combined lenses.

Two converging lenses of the same focal length f are separated by a distance 2f. The axis of the second lens is inclined at angle theta=60^@ with respect to the axis of the first lens. A parallel paraxial beam of light is incident from left side of the lens. Find the coordinates of the final image with respect to the origin of the first lens.
