     149To main characteristics if the electron motion are the coordinate and the velocity. This program it is a solution of a task which is written below. All units for the inputvalues are in CGS system. Between two coaxial rings, charged with q1=q2=1nC and their radius are equal to r1=1cm and r2=2cm, are located at distance 5 cm between each other. At halfway between the rings is located electron with initial energy equal to 0. Find the dependencies between the
     150velocity(energy)and the time,and electron coordinate with time. Also plot the phase trajectory V(x). And explain the resultants.
