Question

determine the resultant of a 50N and 120N force acting at right angle to each other

Answer 1

Drawing the vectors for each of the forces produces a right trangle. The resultant force is the magnitude of the hypotenuse of the triangle, which can be determined by the Pythagorean Theorem:

Result=\[\sqrt{50^{2}+120^{2}}=\sqrt{16,900}=130 N\]
