Answer 1

Answer:

For a telescope, lens L2 is chosen as objective, as its aperture is largest. The lens L3 is chosen as eye piece as its focal length is smallest.

Fro a microscope, lens L3 is chosen as objective because its focal length is smallest. Lens L1 serves as eye piece because its focal length is not largst. This is required to secure greater magnifying power of the microscope.
