Given:
focal length =20cm
The following observations are noted wrong :
case III:
object position =u=40cm
When object is plaed on C we should get image position on C only
V=40cm
Case 5:
Object position=u=35cm
When object is placed between F and C we get image beyond C. so image position should be greater than 40cm.
Case 6:When object position is between P and F we get Image on the same side of lens,so V should be negative.
