Answer :

A compound microscope produces an angular magnification of [(25/f_{e}) + 1]

where,

f_{e} = focal length of the eyepiece

It can be inferred that if f_{e} is small, then angular magnification of the eyepiece will be large.

The angular magnification of the objective lens of a compound microscope is given as

1/(|u_{0}|f_{0})

Where, u_{o} = object distance for the objective lens

f_{o} = focal length of the objective

The magnification is large when u_{o} > f_{o}. In the case of a microscope, the object is kept close to the objective lens. Hence, the object distance is very little. Since, u_{o} is small, f_{o} will be even smaller. Therefore, f_{e} and f_{o} are both small in the given condition.
