Three forces $\displaystyle \mathrm{F}_1=10 \mathrm{~N}, \mathrm{~F}_2=8 \mathrm{~N}, \mathrm{~F}_3=6 \mathrm{~N}$ are acting on a particle of mass $\displaystyle 5$ kg . The forces $\displaystyle \mathrm{F}_2$ and $\displaystyle \mathrm{F}_3$ are applied perpendicularly so that particle remains at rest. If the force $\displaystyle F_1$ is removed, then the acceleration of the particle is:
