Answer 2

Option(b)

The position of the object placed so that the image formed is a real image of the same size as the object is at a distance of twice the focal length

Step-by-step explanation:

In this case, if the object is to be placed in such a way that the image thus formed by the object is real image of the same size so, the position of the object is at a distance twice of the focal length .

So the object is said to be in position at a distance of two times of its focal length i.e., it can be represented as 2f
