Question

Which position of the object will produce a magnified virtual image, if a concave mirror of focal
length 15 cm is being used?​

Answer 1

Now, to obtain magnified and virtual image from concave mirror object should be kept between focus and pole of mirror. Since, the focal length of concave mirror is 15 cm away, thus object should be kept within 15 cm of concave mirror of reflecting surface.
