Question
Write the definition of electrostatic potential. Tell whether it is a vector or a scalar quantity ? Also write its SI unit and dimensional formula.
✓

Answer

→"Work done in bringing unit positive charge from infinity to the given point in the electric field against the electric field is called electrostatic potential ( $V$ ) at that point."
OR
→"In the region of static electric field, electric potential at any point means work done by external force in bringing unit positive charge from infinity to that point, without acceleration."
→Electrostatic potential is a scalar quantity.
→Its SI unit is : V (Volt) OR J/C.
→Its DF (Dimensional Formula) is $M ^1 L^2 T^{-3} A^{-1}$
