When photographing a distant point source in the photograph, due to the low quality of the lens and the photographic material used, a light circle with a diameter of d = 0.1 mm is obtained. From what maximum distance can two point sources, located at a distance l = 1 cm from each other, be photographed under the same conditions, so that their images do not overlap in the photograph? Lens focal length F = 5 cm.
