The resultant force is calculated by subtracting the smaller force from the larger force in the appropriate direction. In this case, the larger force is 15 N and the smaller force is 10 N, both acting in opposite directions. Therefore, the resultant force is 15 N - 10 N = 5 N, which is in the direction of the larger force (southward).
