  • b)
    It forms virtual erect and enlarged image.
  • c)
    It forms virtual, erect, and diminished image.
  • d)
    It forms real, inverted and enlarged image.

Verified Answer
Read the passage and note the following observations. Answer the quest...
you can see, case (iii); here both the object and the image distances are 30cm .but we know this is possible only case when object kept at 2f, so, 2f = 30cm => f = 15cm
(b) use lens formula for finding incorrect observations.
1/v - 1/u = 1/f
see last observation (v)
u = -15
f = +15
then, 1/v = 1/15 - 1/15 = 0 = 1/∞ => v = ∞
but v = 70cm is given hence, observation (v) is wrong.
(c) obviously case 3, in this case size of image is equal to size of object due to image distance distance is equal to object distance from pole.
