Answer:
Screen should be placed 36 cms (at Centre of Curvature) from the mirror if the candle is placed in between C (centre of curvature) and F (Focal Length). The nature of the object is real and inverted and the magnification is 4/3
Explanation:
According to concave mirror diagrams, if the object is placed in between C and F, the image (Real and Inverted) will be formed at C. Therefore the object distance is (-36) cms from the mirror. And the height of the image formed is 4/3 times the size of the candle.
If candle is moved closer to the mirror, screen has to be pushed away from the mirror.
I hope this helps you.
