Parallel beams of similarly charged particles are shot from two atomic accelerators L = 34 meters apart, as shown in the figure below. If the particles were not deflected, the beams would be 
meters apart. However, because the charged particles repel each other, the beams follow the hyperbolic path 
/>, for some k. Find k.
