Let me help you with this one.. This question has two parts:
1. If the mirror is broken into two pieces, its focal length remains the same i-e, 15 cm. Focal length changes when there is change in the radius of curvature of the mirror. In this case, radius of curvature is same. Thus focal length also remains the same.
2. If the mirror is broken into two pieces, each part of the mirror will act as an independent mirror. Thus each broken part will reflect its own image. In this case, mirror is broken into two parts, hence two separate images will be formed.
Hope it will help you.
