I wish to obtain an erect image of an object, using a concave mirror of focal length 15cm. What should be the range of distance of the object from the mirror? What is the nature of the image? Is the image larger or smaller than the the object? Draw a ray diagram to show the image formation in this case?

Range of distance:  object placed between the focal point and vertex, i.e. 15 cm from the mirror
Nature of image: Virtual
