Was really struggling to do this question , so decided to ask for help here

A compound microscope has and objective lens focal length of 0.15 cm and eyepiece lens focal length of 1.4cm . The distance between the lenses is 20 cm . It is adjusted for relaxed viewing (i.e. the final image is an infinite distance from the eye).

Part A

Find the lateral magnification produced by just the objective lens.

Part B

Find the angular magnification produced by just the eyepiece lens.
