A student microscope has a 10X objective and a 15X eyepiece. A student is using the microscope to view a thin slice of an apple. The cells in the apple have a diameter of 0.10 mm. Assume a length L = 160 mm.

a. How far from the objective lens should the apple slice be placed?

***Please use the equation M₀ = -L/f₀ = -L/d₀

b. How does the angular size of a cell when viewed through the microscope compare to the angular size of a 19 mm diameter penny at a distance of 25 cm?

Please show all steps and explain thoroughly.
