Respuesta :
The potential at a point on the line will be,[tex]\rm E_{net}=\frac{5Kq}{r}[/tex].The net potential is the algebraic sum of the electric potential.
What is the electrical potential difference?
The amount of work performed in an electrical field to move a unit charge from one location to another is defined as the electrical potential difference.
In other terms, the potential difference is the difference in electric potential between two charged substances.
The traditional current flow is from positive to negative terminals, indicating the movement of positive charges in that direction.
[tex]\rm E_1 = \frac{Kq}{r} \\\\ E_2=\frac{K(4q)}{r}[/tex]
The potential at a point on the line is found as;
[tex]\rm E_{net}=E_1+E_2 \\\\\ E_{net}=\frac{Kq}{r} +\frac{K(4q)}{r} \\\\E_{net}=\frac{5Kq}{r}[/tex]
Hence, the potential at a point on the line will be,[tex]\rm E_{net}=\frac{5Kq}{r}[/tex]
