At short distances ( less than 1.7 fm or so ), the attractive nuclear force is stronger than the repulsive Coulomb force between protons; it thus overcomes the repulsion of protons within the nucleus.

The " magnetic " force between the two lines of charge per unit length in the lab frame is that total force per unit length minus the Coulomb force per unit length as measured in the lab frame,
33.
An "'electric field "'is a vector field that associates to each point in space the Coulomb force that would be experienced per unit of electric charge, by an infinitesimal test charge at that point.
34.
There are only three forces on each sphere, tension, a Coulomb force and gravity, and you know which direction each force is in ( or can figure it out by drawing what you know about the setup ).
35.
The strength and direction of the Coulomb force on a test charge } } depends on the electric field that it finds itself in, such that " q " "'E "'} }.
36.
If you assume that each sphere has the same charge you can find the charge from the magnitude of the Coulomb force and the distance between the spheres . & mdash; Talk 17 : 26, 13 October 2005 ( UTC)

Photons diffused from the hot, overdense regions of plasma to the cold, underdense ones : they dragged along the protons and electrons : the photons pushed electrons along, and these, in turn, pulled on protons by the Coulomb force.
38.
However, the Coulomb force between protons has a much greater range as it varies as the inverse square of the charge separation, and Coulomb repulsion thus becomes the only significant force between protons when their separation exceeds about 2 to 2.5 fm.
39.
The electric potential energy of given configuration of charges is defined as the work which must be done against the Coulomb force to rearrange charges from infinite separation to this configuration ( or the work done by the Coulomb force separating the charges from this configuration to infinity ).
