In a compound microscope, the focal length of the objective lens is $2\text{cm}$ and that of the eyepiece is $5\text{cm}$. When the object is kept at $3\text{cm}$ in front of the objective lens, the final image is formed at a distance of $50\text{cm}$ from the eyepiece. Magnifying power of the compound microscope is -

Q. In a compound microscope, the focal length of objective lens is $1.2\text{cm}$ and that of eyepiece is $3\text{cm}$. When the object is kept at $1.25\text{cm}$ in front of the objective, the final image is formed at infinity. Magnifying power of the compound microscope is

Q. In a compound microscope, the focal length of the objective lens is $1.2\text{cm}$ and the focal length of the eyepiece is $3\text{cm}$. When the object is kept at $1.25\text{cm}$ in front of the objective lens, the final image is formed at infinity. The magnifying power of the compound microscope is -

Q. In a compound microscope, the focal length of the objective lens is $0.5\text{cm}$ and that of the eyepiece is $5\text{cm}$. The intermediate real image of the object is formed at a distance of $15.5\text{cm}$ from the objective lens. If the final image is formed at a distance of $25\text{cm}$ from the eyepiece, what is the magnifying power of the compound microscope?

Q. The focal length of objective lens and eyepiece for a compound microscope are $0.95$ and $5$ cm and they are placed at $20$ cm from each other final image is formed at $25$ cm in eyepiece find the magnifying power of the microscope?

Q. The length of a compound microscope is 14 cm and its magnifying power when final image is formed at near point is 25. If the focal length of eyepiece is 5 cm, the focal length of objective lens is:
