For the object placed at x – infinity
The following figure shows a beam of light converging at point P. when a convex lens of focal length 16 cm is introduced in the path of the beam at a place O shown by dotted line such that OP becomes the axis of the lens, the beam converges at a distance x from the lens. The value x will be equal to
