The gravitational field in a region is given by $\displaystyle \overrightarrow{\mathrm{g}}=5 \mathrm{~N} / \mathrm{kg} \hat{i}+12 \mathrm{~N} / \mathrm{kg} \hat{j}$. The change in the gravitational potential energy of a particle of mass $\displaystyle 2$ kg when it is taken from the origin to a point ($\displaystyle 7$ m, -$\displaystyle 3$ m) is :
