An object is positioned $20\,\text{cm}$ in front of a thin converging lens. The scale diagram indicates that the lens produces a real, inverted image. Which row states the focal length of the lens and the distance of the image from the lens?
- Afocal length $4.0\,\text{cm}$, distance of image $5.0\,\text{cm}$
- Bfocal length $5.0\,\text{cm}$, distance of image $4.0\,\text{cm}$
- Cfocal length $8.0\,\text{cm}$, distance of image $10.0\,\text{cm}$
- Dfocal length $10.0\,\text{cm}$, distance of image $8.0\,\text{cm}$
