Answer:
Object should be place between Center of curvature (C) and Focal point (F)
Explanation:
When we place object between C and F
=> we get image beyond C
=> real and inverted
=> magnified (enlarged) image
so here in question they gave magnification = -3
m = -ve sign represents real image
m = 3 means m > 1 --- enlarged image
