Three non-zero forces, F1, F2 , and F3, are acting on an object. Forces F1 and F3 have opposite direction, and both are perpendicular to F2. Under which conditions, if any, will the object be in equilibrium? https://tcan4424-oakcliff-ccl.gradpoint.com/Resour...

a.The magnitudes of F1 and F3 must be equal, and must be one half the magnitude of F2.

b.The magnitudes of F1 and F3 must be equal, and must be one third the magnitude of F2.

Since the forces are non-zero, there will be always a resultant force even if F1 and F3 becomes equal and opposite. If F1 and F3 are equal and opposite they will cancel out and resultant will be equal to F2, which is non-zero.
