If two deuterium nuclei (charge +e, mass3.34*10-27kg) get close enough together, the attractionof the strong nuclearforce will fuse them to make an isotope ofhelium, releasing vastamounts of energy. The range of this force isabout10-15 is the principle behind the fusion reactor.Thedeuterium nuclei are moving much too fast to be containedbyphysical walls, so they are confined magnetically. a)How fast would two nuclei have to move sothatin a head-on collision they would get close enough to fuse?(Treatthe nuclei as point charges, and assume that a separationof1*10-15 is required for fusion.)

a)
How fast would two nuclei have to move sothatin a head-on collision they would get close enough to fuse?(Treatthe nuclei as point charges, and assume that a separationof1*10-15 is required for fusion.)
