Correct
If the resultant passes through B, the original system must be equivalent to the new system shown (a single force passing through
point B with no accompanying couple).

Incorrect
Now find M (the magnitude of the couple in the original system) so that the moments about point B are the same in both systems.
Answer: M = i
