A cylindrical tube has a length of 60 cm. Three identical convex lenses, each of focal length `f = 10` cm are fixed inside the tube, one at each of the ends and one at the centre. One end of the tube is placed 10 cm away from a point source. The device casts an image of the object. How much does the image shift when the tube is moved away from the source by 10 cm.
