What will each newly formed cell form around the chromosomes

it will form a Telophase

Explanation:

During telophase, the newly separated chromosomes reach the mitotic spindle and a nuclear membrane forms around each set of chromosomes, thus creating two separate nuclei inside the same cell. As Figure 4 illustrates, the cytoplasm then divides to produce two identical cells.

A nuclear envelope forms around each set of chromosomes, and a nucleolus forms in each of the newly forming cells. Copied DNA coils into chromosomes ... Kinetochore fibers move chromosomes to the cell's center.
