the maximum magnification which can be obtained with the help of a simple microscope is 6. If a point object is placed at a distance 3 cm from the microscope, then what was the position of image?

Q. An object is placed at a distance $u$ from a simple microscope of focal length $f$. The angular magnification obtained depends

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

Q. An object is to be seen through a simple microscope of focal length $10\text{cm}$. Where should the object be placed to produce maximum angular magnification? (The least distance for clear vision is $30\text{cm})$.

Q. An object is to be seen through a simple microscope of focal length 12 cm. Where should the object be placed so as to produce maximum angular magnification? The least distance for clear vision is 25 cm.

Q. In a compound microscope the objective and eye-piece have focal lengths of $9.5cm$ and $5cm$ respectively, and are kept at a distance of $20cm$ . The last image is formed at a distance of $25cm$ from eye-piece. What is the total magnification of the microscope?
