Problem P. 4602. (January 2014)

P. 4602. Two lenses of optical power of 10 dioptres are placed such that their principal axis coincide. There is a well-illuminated object 12-cm from one of them - the other lens is on the other part of the lens. The other lens forms a virtual, 50-times magnified image of the object. By what distance does this lens need to be moved in order to create a 50-times magnified image on a screen?
