The electric field strength depends only on the x, y and z coordinates according to the law\[E=\frac{a\left( x\hat{i}+y\hat{j}+z\hat{k} \right)}{{{\left( {{x}^{2}}+{{y}^{2}}+{{z}^{2}} \right)}^{{3}/{2}\;}}}\], where\[a=122.5\]SI unit and is a constant. Find the potential difference (in volt) between (3, 2, 6) and (0, 3, 4).
