A thin convex lens of focal length `5` cm is used as a simple microscope by a person with normal near point `(25"cm")` . What is the magnifying power of the microscope.?

Assertion(A): A convex lens of focal length 30 cm can’t be used as a simple microscope in normal setting. Reason (R): For normal setting, the angular magnification of simple microscope is M=D/f

A convex lens of focal length 6.25cm is used as a simple microscope. To obtain maximum magnification, the object distance should be
