What is the vector sum of these two forces? Or, what is the resultant of these two forces? We begin my making a careful diagram with some scale chosen so that one centimeter represents, perhaps, 10 N. In that case, the upward arrow in the diagram would be 3 cm long and the right arrow in the diagram would be 4 cm long. The resultant -- the vector sum -- of these two vectors is the diagonal of the rectangle (or parallelogram) they form. We would measure this arrow to be 5 cm long on our diagram; that means the magnitude of the resultant is ? N (remember, 1 cm represents 10 N of force).
