Question

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