A lady uses $+1.5\text{D}$ glasses to have normal vision from $25\text{cm}$ onwards. She uses a $20\text{D}$ lens as a simple microscope to see an object. The maximum magnifying power if she uses the microscope together with her glass is (Integer only)

Q. A person uses +1.5 D glasses to have normal vision from 25 cm onward. he uses a +20 D lens as a simple microscope to see an object. What is the maximum magnifying power if he uses the microscope without glasses?

Q. Find the maximum magnifying power of a compound microscope having a $25\text{D}$ lens as the objective, a $5\text{D}$ lens as the eyepiece and a separation of $30\text{cm}$ between the two lenses. The least distance for clear vision is $25\text{cm}$.

Q.

A man with normal near point (25 cm) reads a book with small print using a magnifying glass: a thin convex lens of focal length 5 cm.

(a) What is the closest and the farthest distance at which he should keep the lens from the page so that he can read the book when viewing through the magnifying glass?

(b) What is the maximum and the minimum angular magnification (magnifying power) possible using the above simple microscope?
