Question

In an optics experiment, with the position of the object fixed, a student varies the position of a convex lens and for each position, the screen is adjusted to get a clear image of the object. A graph between the object distance $u$ and the image distance $v$ , from the lens, is plotted using the same scale for the two axes. A straight line passing through the origin and making an angle of $4 5^{\circ}$ with the x-axis meets the experimental curve at $P$ . The coordinates of $P$ will be
