Three coplanar forces, F1\mathbf{F}_1F1, F2\mathbf{F}_2F2, and F3\mathbf{F}_3F3, act on a particle P P\,P of mass 0.5 kg as shown in the diagram below.
Initially, the particle is in equilibrium under the action of these three forces.
If the force F3\mathbf{F}_3F3 is suddenly removed, which of the following is the magnitude of the acceleration of PPP?
532 m s−2\frac{\sqrt{53}}{2}\text{ m s}^{-2}253 m s−2
253 m s−22\sqrt{53}\text{ m s}^{-2}253 m s−2
53 m s−2\sqrt{53}\text{ m s}^{-2}53 m s−2
65 m s−26\sqrt{5}\text{ m s}^{-2}65 m s−2
