Nuclear Physics: In nuclear fusion, two atomic nuclei can merge to form new elements. Atomic nuclei are positively charged, so they repel. However, if they come close enough to "touch" then nuclear forces overcome the electric forces and the nuclei will quickly fuse together. The whole process is over in less than 4.18 x 11s. Consider a head-on collision between two identical nuclei moving directly toward each other with equal speeds. Each nuclei has a mass of 1.8 x 10 26 kg, a radius of 2.3 x 10-15 m, and a charge of +7e. What minimum speed will allow the nuclei to "touch" and fuse together?
