Physics - Geometrical Optics Question with Solution | TestHub

An object viewed from a near point distance of$25 \mathrm{cm}$, using a microscopic lens with magnification$6,$gives an unresolved image. A resolved image is observed at infinite distance with a total magnification double the earlier using an eyepiece along with the given lens and a tube of length$0.6 \mathrm{m}$, if the focal length of the eyepiece is equal to ____$\mathrm{cm}.$
