A point object is placed 60 cm in front of a CONVEX LENS OF FOCAL LENGTH 30 CM. A PLANE MIRROR IS PLACED 10 CM BEHIND THE LENS . WHERE IS THE IMAGE FORMED BY THE SYSTEM?

1/f=1/v - 1/u v=uf/(u+f)   = -60*30/(-60+30)  =60cm with respect to mirrorDistance between lens and mirror= 10 cmSo the virtual image will be at 50  cm in the mirror.We get the image at 50 cm towards the lens again, which behaves as anobject for it!So the object will be at 40 cm for lens that also virtual!So we get final image asv=uf/u+f = 30*40/(30+40) = 17.14285 cm
