If three forces are acting on an object such that north of east, west, and south, what is the resultant force?
A. 10N west
B. 10N east
C. 10N north
D. 10N south
B
must be broken down into the components 14N north and 14N east ( forms a 45-45-90 triangle, making it relatively straightforward to derive the components). The forces in the east-west directions and the north-south directions are then summed, yielding answer B.
