A body of mass $\displaystyle 5$ kg under the action of constant force $\displaystyle \overrightarrow{\mathrm{F}}=\mathrm{F}_x \hat{i}+\mathrm{F}_y \hat{j}$ has velocity at $\displaystyle \mathrm{t}=0 \mathrm{~s}$ as $\displaystyle \vec{v}=(6 \hat{i}-2 \hat{j}) \mathrm{m} / \mathrm{s}$ and at $\displaystyle \mathrm{t}=10 \mathrm{~s}$ as $\displaystyle \vec{v}=+6 \hat{j} \mathrm{~m} / \mathrm{s}$. The force $\displaystyle \overrightarrow{\mathrm{F}}$ is :
