A particle is acted upon by constant forces $4\overline{\mathrm{i}} + \overline{\mathrm{j}} -3\overline{\mathrm{k}}$ and $3\overline{\mathrm{i}} + \overline{\mathrm{j}} - \overline{\mathrm{k}}$ which dis- place it from a point $\overline{\mathrm{i}} + 2 \overline{\mathrm{j}} + 3\overline{\mathrm{k}}$ to the point $5\overline{\mathrm{i}} + 4\overline{\mathrm{j}} + \overline{\mathrm{k}} .$ The work done in standard unity by the forces is given by
