Answer:
Explanation:
Electric forces exist among stationary electric charges; both electric and magnetic forces exist among moving electric charges. ... The magnetic force between two moving charges may be described as the effect exerted upon either charge by a magnetic field created by the other.

Answer:
Total electric potential, 
Explanation:
It is given that,
First charge, 
Second charge, 
Distance of first charge from origin, 
Distance of second charge from origin, 
We need to find the total electric potential at the origin. The electric potential at the origin is given by :



V = 1321826.08 V
or

So, the total electric potential at the origin is
. Hence, this is the required solution.
As AL2006 correctly pointed out the formula is 1/2 kx^2. I was thinking of force and work is the integral of force over the distance applied. So now

and
