Five forces ${\overrightarrow{\mathrm{F}}}_1,{\overrightarrow{\mathrm{F}}}_2,{\overrightarrow{\mathrm{F}}}_3,{\overrightarrow{\mathrm{F}}}_4$ and ${\overrightarrow{\mathrm{F}}}_5$ acting on a particle of mass 2.0 kg so that, it is moving with $4\mathrm{m}/{\mathrm{s}}^2$ in east direction. If ${\overrightarrow{\mathrm{F}}}_1$ force is removed, then the acceleration becomes $7\mathrm{m}/{\mathrm{s}}^2$ in north, then the acceleration of the block if only ${\overrightarrow{\mathrm{F}}}_1$ is acting will be :
