A long rectangular slab of transparent medium of thickness 'd' placed a table with its length parallel to the x-axis and width parallel to the y-axis. A ray of light travelling in air makes a near normal incidence on the slab as shown. Taking the point of incidence as origin (0,0,0). The refraction index  of the medium varies as mu equals fraction numerator mu subscript 0 over denominator 1 minus open parentheses x over r close parentheses end fraction , where mu subscript 1 and r left parenthesis greater than d right parenthesis are constants. The refractive index of airis 1

The x-coordinate of the point A where the ray intersects the upper surface of the slab air boundary is
