The focal length of the objective and eye piece of a telescope are respectively 60 cm and 10 cm . The magnitude of the magnifying power when the image is formed at infinity is

Let the minimum external work done in shifted a particle form centre of earth to earth's surface be W_(1) and that form surface of earth to infinity be W_(2) . Then (W_(1))/(W_(2)) is equl to

Two convex lesses of power 2 D and 5 D are separated by a distance 1/3m m The power of the optical system formed is

Two convex lenses of powers 4D and 6D are separated by a distance of (1)/(6)m . The power of the optical system so formed is
