Laws Of Motion

Three forces \(F_{1}=10 \mathrm{~N}, F_{2}=8 \mathrm{~N}, \mathrm{~F}_{3}=6 \mathrm{~N}\) are acting on a particle of mass \(5 \mathrm{~kg}\). The forces \(\mathrm{F}_{2}\) and \(\mathrm{F}_{3}\) are applied perpendicularly so that particle remains at rest. If the force \(F_{1}\) is removed, then the acceleration of the particle is:
