... All nuclei contain protons and neutrons (exception - hydrogen-1 has no neutrons). Since protons are positively charged, it would be expected that they would repel and separate, but this does not occur. A force holds them together. The nuclear force is an attractive force that acts between all nuclea ...

... Problem 3. Nobel laureate Richard Feynman once said that if two persons stood at arm’s length from each other and each person had p = 1% more electrons than protons, the force of repulsion between them would be enough to lift a “weight” equal to that of the entire Earth. Carry out an order of magnit ...
