Hey !
_____________________________________________
focal length of objective greater than the focal length of eye piece in a telescope Because the magnification is increases .
________________________
Ex : - A 50 mm eyepiece in a telescope with a 1500 mm focal length would magnify objects 48 times.
A 4 mm eyepiece in the same telescope would magnify 300 times.

The objective lens of a telescope forms an real image of the night sky, the size of that image is in proportion to the focal length of the objective lens.
this is a round about way of saying the the magnification of a lens is inversely proportional to the focal length.
