Answer:
The electric potential (voltage) [tex]V[/tex] produced by a point charge [tex]Q[/tex], at any point in space, is given by the following equation:
[tex]V=k\frac{Q}{r}[/tex]
Where:
[tex]k=8.99(10)^{9} Nm^{2}/C^{2}[/tex] is the Coulomb's constant
[tex]r[/tex] is the distance
The result is a scalar quantity, is defined as the electric potential energy per unit of charge and determines the electric influence exerted by the charge on that point of space.
Answer:
v=k*q/d
Explanation:
The formula v=k*q/r is also correct but in this case v=k*q/d was given as a choice.
