Question

An object is placed so that the image formed is a real image of the Sam size as the object. What is the position of the object?
A. At the focal point
B. At a distance of twice the focal length
C. Greater than the focal length but less than twice the focal length
D. At a distance less than the focal length

Answer 1

Answer:

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

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 2
