Answer:
D.The potential energy per unit charge
Explanation:
Electric potential of a charged particle:
It is scalar quantity because it has magnitude but it does not have direction.
It is the amount of work done required to move a unit positive charge from reference point to specific point in the electric field without producing any acceleration.
Mathematical representation:
Where W= Work done
= Unit positive charge
Other formula to calculate electric field:
Where K=
It can be defined as potential energy per unit charge.
Hence, option D is true.
