(3) On increasing the focal length of the eyepiece the image would be smaller.
hence the correct option is b.
(4) We know that the magnification of the compound microscope is
M = MoMe
where Me is the angular magnification of the eyepiece and it is defined as
Me = 25/fe
where fe is the focal length of the eyepiece. On increasing the focal length the angular magnification of eyepiece will decrease which decrease the total magnification of the microscope.
Hence the image will be smaller.
