A plano-convex glass lens `(mu_(g)=3//2)` of radius of curvature` R=10cm` is placed at a distance of b from a concave lens of focal length 20cm. What should be the distance a of point object O from the plano-convex lens so that position of final image is independent of b?

A plano convex glass lens (mu_(g) = 3//2) of radius curvature R = 10 cm is placed at a distance of b from a concave lens of focal length 20 cm. what should the distance 'a' of a point object O from the plat convex lens so that the position of final image always at same distance from concave lens
