This question involves the concepts of the law of conservation of momentum.

The magnitude of the final momentum of the eight ball is "0.22 N.s".

According to the law of conservation of momentum:

[tex]P_{i1}+P_{i2}=P_{f1}+P_{f2}[/tex]

where,

[tex]P_{i1}[/tex] = initial momentum of the cue ball = 0.23 N.s

[tex]P_{i2}[/tex] = initial momentum of the eight ball = 0 N.s (since ball is initially at rest)

[tex]P_{f1}[/tex] = final momentum of the cue ball = 0.01 N.s

[tex]P_{f2}[/tex] = final momentum of the eight ball = ?

Therefore,

[tex]0.23\ N.s + 0\N.s = 0.01\ N.s+P_{f2}\\\\P_{f2} = 0.22\ N.s[/tex]
