Consider two forces of equal magnitude acting on a point.
(a) When the magnitude of the resultant is the sum of the magnitudes of the two forces, make a conjecture about the angle between the forces.
(b) When the resultant of the forces is 0, make a conjecture about the angle between the forces.
(c) Can the magnitude of the resultant be greater than the sum of the magnitudes of the two forces? Explain.
