Two point charges are on the y axis. A 4.50-σC charge (
) is located at y=1.25 cm (
) , and a -2.24-σC charge (
) is located at y=-1.80 cm (
).
The total electric potential at the origin is
.
How to calculate the total electric potential at the origin?
The total electric potential at some point due to several point charges is represented by:

Here,
(Columbic constant)
The total electric potential at point
is the sum of the potentials due to
and
will be:

Substituting the values, we get:

Hence, the total electric potential at the origin is
.4
