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

The fundamental frequency of a string is given by:
where L is the string's length, T the tension and
the linear density of the string.
We can see that f1 is proportional to the square root of T:
.
This means that if the new tension is half the initial value, the new fundamental frequency will be proportional to
So, the new fundamental frequency will be
where L is the string's length, T the tension and
We can see that f1 is proportional to the square root of T:
This means that if the new tension is half the initial value, the new fundamental frequency will be proportional to
So, the new fundamental frequency will be
