Please explain, walkthrough, and show equations.

The focal length of the objective lens in a microscope is 0.270 cm, and an object is placed 0.275 cm from the objective.

a. How far from the objective lens will the objective image be formed?

b. If the image of this object is viewed with the eyepiece adjusted for minimum eyestrain (image at the far point of the eye) for a person with normal vision. What is the needed focal length of the eyepiece lens if the distance between the objective and the eyepiece lenses is 17.5 cm?

c. What is the angular magnification of this microscope? (approximation)

d. If a near sighted person with a far point of 1.85 m looked through this microscope what would the distance between the two lenses need to be to get minimal eyestrain?

e. And what would that magnification be? (approximation)
