A dipole of dipole moment $\overrightarrow{P}=2\hat{\mathrm{i}}-3\hat{\mathrm{j}}+4\hat{\mathrm{k}}$ is placed at point $A\left(2,-3,1\right)$. The electric potential due to this dipole at the point $B\left(4-1,0\right)$ is equal to (all the parameters specified here are in $\mathrm{S}.\mathrm{I}.$ units),
