1.	A convex lens of focal length 10cm is placed at a distance of 12 cms from a wall how for from the lens should an object be placed so as to form its real image on the wall
Answer» SAY that v=12cm1/f=1/v -1/u1/u=1/v- 1/f1/u=1/12-1/101/u=5-6/60u=-60cmSo the object should be PLACED at 60cm from the lens to obtain a REAL image on the wall
