Physics - Geometrical Optics Question with Solution | TestHub

In an experiment to determine the focal length$\mathrm{f}$of a concave mirror by the$\text{u}-\mathrm{\upsilon }$method, a student places the object pin$\mathrm{A}$on the principal axis at a distance$\mathrm{x}$from the pole$\mathrm{P}$. The student looks at the pin and its inverted image from a distance keeping his/her eye in line with$\mathrm{PA}$. When the student shifts his/her eye towards left, the image appears to the right of the object pin. Then
