Answer : The correct option is, [tex]V=k\frac{q}{d}[/tex]
Explanation :
Electric potential : It is defined as the amount of work needed to move a unit of positive charge from a point charge (reference) to a specific point inside the field.
Mathematically it is written as :
[tex]V=k\frac{q}{d}[/tex]
where,
V = electric potential
q = electric charge
d = distance between the reference point and the specific point
k = [tex]\frac{1}{4\pi \epsilon_o}[/tex] = k = constant
Hence, the formula is, [tex]V=k\frac{q}{d}[/tex]
