Physics (Ms Eduncle.com 12.) Two thin convex lenses of focal lengths f, and f, are separated X V1 d Dy a horizontal distance d (where d < f,, d < i.) and their centres are displaced by a ven separation A as shown in the figure. Taking the origin of coordinates, O, at the centre of thes lens, the x and y-coordinates of the focal point of this lens system, for a parallel beam of re coming from left, are given by X=+y= A f,f2 f,+f2 (A) x = (B) Xf-dYt+ y = A Xla +d(t,-d) At-d) f+f-d ,+f2-d ff2 +d(f,-d) y =0 f+2-d (C) (D) y = 0 X =
