Answer: 2 cm
Explanation:
Given , for a converging lens
Focal length :
Height of object :
Object distabce from lens :
Using lens formula: , we get
, where v = image distance from the lens.
On solving aboive equation , we get
Formula of Magnification : , where h' is the height of image.
Put value of u, v and h in it , we get
Hence, the height of the image is 2 cm.
