A convex lens of focal length 1.5m is placed in a system of coordinate axis such that its optical centre is at origin and principa, axis coinciding with the x-axis. An object and a plane mirror are arrange on theh principal axis as shown in figure. Find value of d (in m) so that y-coordinate of image (after refraction and reflection ) is 0.3m. (Take `tan theta=0.3)`
