Answer:
Since you are asking for magnitude only, 12.6 units is the resultant. If you were looking for the full answer, 12.6 units North would be your answer
Step-by-step explanation:
There there are 2 forces acting in the north direction add them up 5.4+9.3
this equals 14.7 since there is also something acting in the opposite direction, subtract that from the total of the previous two, 14.7-2.1,
and your final answer will be 12.6 units
