Two convex lenses of same focal length but of aperture D_1 and D_2(D2 lt D1) ,are used as the objective lenses in two astronomical telescopes having identical eyepieces. what is the ratio of their resolving powers? Which telescope will you prefer and why ? Give reason.

The focal length of the objective an astoomical telescope is 75 cm and that of the eye-piece is 5 cm.If the final image is ofrmed at the least distance of ditinct vision from the eye,calculate the magnifying power of the telescope.
