Amicroscope has an objective lens with a focal length of 1.82 mm. the lenses are 47.8 cm apart what should the focal length of the eyepice be if i want the microscope to have an angular magnifica tion of -2000?

focal length of eye lens is 3.28 cm

Explanation:

As we know that the magnification of the microscope is given by the formula

now we will have

D = 25 cm

M = 2000

now we need to solve above equation to find focal length of eye lens

so here we will have

i think the answer is a and b

i wish you luck
