Angular resolving power of human eye is

What is the resolving power of human eye.

Resolving power of a microscope is

A microscope is used to resolve two self luminous objects separated by a distance of 5 xx 10^(-5)cm and placed in air. What should be the minimum magnifying power of the microscope in order to see the resolved images of the objects? The resolving power of the eye is 1.5 and teh least distance of distinct vision is 25 cm.

Aperture of the human eye is 2 mm. Assuming the mean wavelength of light to be 5000 Å, the angular resolution limit of the eye is nearly
