A typical carbon nucleus contains 6 neutrons and 6 protons. The 6 protons are all positively charged and in very close proximity, with separations on the order of 10-15 meters, which should result in an enormous repulsive force. What prevents the nucleus from dismantling itself due to the repulsion of the electric force?
a. The attractive nature of the strong nuclear force overpowers the electric force.
b. The weak nuclear force barely offsets the electric force.
c. Magnetic forces generated by the orbiting electrons create a stable minimum in which the nuclear charged particles reside.
d. The attractive electric force of the surrounding electrons is equal in all directions and cancels out, leaving no net electric force.
What prevents gravity from pulling you through the ground to the center of the Earth? Choose the best answer. (a) The density of matter is too great. (b) The positive nuclei of your body’s atoms repel the positive nuclei of the atoms of the ground. (c) The density of the ground is greater than the density of your body. (d) Atoms are bound together by chemical bonds. (e) Electrons on the ground’s surface and the surface of your feet repel one another.
Two positively charged protons in a Helium nucleus are separated by about 2 x 10^-15 m. Use Coulomb's law to find the electrical force of repulsion between the two protons. This result will give you an indication of the strength of the STRONG nuclear force.
