The same electromagnetic force that draws opposite charged electrons and protons together tries to push the protons (which all have the same charge) away from each other.

The result helped show that the strengths of the strong, weak and
electromagnetic forces were very nearly the
same in the early universe, even though today the strong
force is far more powerful than the other two.
BICEP2's value of r suggests that this was the
same energy scale at which all the
forces of nature except gravity (the
electromagnetic, strong and weak
forces) might have been unified into a single
force — an idea called grand unified theory.
Starting with the assumption baked into James Clerk Maxwell's theory of the
electromagnetic force, formulated 40 years earlier, that light always travels at the
same speed, the special theory of relativity demonstrated how two observers in motion relative to each other will not perceive ruler lengths and clock ticks the
same way.
Due in part to the
forces» relative simplicity, scientists have previously been able to solve the equations behind gravity and
electromagnetic interactions, but the strength of the strong interaction makes it impossible to solve the equations in the
same way.
The
electromagnetic force is a
force of infinite range which obeys the inverse square law, and is of the
same form as the gravity
force.»
It is the
same basic formula so the
same holds true here for
electromagnetic forces.
