282928 The magnifying power of a telescope is 9 . When it is adjusted for parallel rays, the distance between the objective and the eye piece is found to be \(20 \mathrm{~cm}\). The focal length of lenses are

282905 Telescope has an objective of focal length 100 \(\mathrm{cm}\) and an eyepiece of focal length \(5 \mathrm{~cm}\). the least distance of distinct vision is \(25 \mathrm{~cm}\). The telescope is focussed for distinct vision of a scale \(3 \mathrm{~m}\) away from the objective. The magnification produced is

282906 There are four lenses \(L_1, L_2, L_3\) and \(L_4\) of focal lengths, 2, 4, 6 and \(8 \mathrm{~cm}\) respectively. Two of these lenses form a telescope of length \(10 \mathrm{~cm}\) and magnifying power 4 . The objective and eye lenses are
