Two protons in an atomic nucleus are typically separated
by a distance of 2 & 10"15 m. The electric repulsion force
between the protons is huge, but the attractive nuclear
force is even stronger and keeps the nucleus from bursting
apart. What is the magnitude of the electric force between
two protons separated by 2.00 & 10"15 m?
