Question

Which equation is used to calculate the electric potential in an electric field from a point charge?

Answer 1

v=k*q/d

Step-by-step explanation:

The formula v=k*q/r is also correct but in this case v=k*q/d was given as a choice.

Answer 2

The electric potential (voltage)
`V` produced by a point charge
`Q`, at any point in space, is given by the following equation:

`V=k(Q)/(r)`

Where:

`k=8.99(10)^(9) Nm^(2)/C^(2)` is the Coulomb's constant

`r` 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.
