With reference to the electric potential, which of the following statements is/are correct ?
1. It is a scalar quantity.
2. It is a vector quantity.
Select the correct answer using the codes given below.

Explanation

Electric potential is defined as the amount of work done in moving a unit positive charge from infinity to a specific point in an electric field. Since both work and charge are scalar quantities, electric potential is also a scalar quantity. It possesses magnitude but does not have a specific direction.

Statement 1 is correct: Electric potential at a point depends only on the work done per unit charge, which is independent of direction.
Statement 2 is incorrect: It is not a vector. While the electric field (the negative gradient of potential) is a vector quantity, the potential itself is scalar.

The SI unit of electric potential is the Volt (V), which is equivalent to one Joule per Coulomb (J/C).
