Answer:
p ≈ f_ objective Therefore for the object to be in focus it must be close to the focal length
Step-by-step explanation:
A microscope is an optical instrument that uses two lenses, or a long focal length objective lens that forms a real image of the object and an eyepiece that forms a virtual image of the object. Therefore for the object to be in focus it must be close to the focal length
p ≈ f_ objective
p distance objetive
