(N/A) The $SI$ unit of electrostatic potential energy is the Joule $(J)$.
Electrostatic potential energy is a form of energy, and the dimensional formula for energy is derived from the work done, which is $Force \times Displacement$.
The dimensional formula for force is $[M^1 L^1 T^{-2}]$ and for displacement is $[L^1]$.
Therefore, the dimensional formula for energy is $[M^1 L^1 T^{-2}] \times [L^1] = [M^1 L^2 T^{-2}]$.
