Question

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

Answer 1

Answer:

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

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

Answer 2

Answer:

At the distace twice the focal length of a convex mirrow.
