It should be in Coulombs.TSny said:If you want the force to be in units of Newtons, what should be the units for electric charge?
Yes. It looks like you made a minor error in expressing the two charges in terms of Coulombs. Check to see if you missed a factor of 10-19.Randell Julius said:It should be in Coulombs.
The value we used for e was 1.602e-19 CoulombsTSny said:Yes. It looks like you made a minor error in expressing the two charges in terms of Coulombs. Check to see if you missed a factor of 10-19.
Yes. Note that e occurs twice, once for each charge. So, how many factors of 1.602 x 10-19 occur in the numerator of the force calculation?Randell Julius said:The value we used for e was 1.602e-19 Coulombs
2 factors of 1.602 * 10-19.TSny said:Yes. Note that e occurs twice, once for each charge. So, how many factors of 1.602 x 10-19 occur in the numerator of the force calculation?
Okay thank you very much.TSny said:OK. My mistake. Since your answer was off by exactly a factor of 10-19, I assumed (wrongly) that you had missed a factor of 10-19 in substituting for the charges. Now that I have grabbed my calculator and checked your work, I'm getting the same answer as you. The distance for d given in the problem looks way too small to be reasonable. (It is much less than the size of a nucleus!) So, I think there must have been a misprint in the problem statement for the distance d.
An alpha particle is a type of particle that consists of two protons and two neutrons, which is equivalent to a helium nucleus. It is emitted by radioactive materials during the process of radioactive decay.
An alpha particle approaches a gold nucleus through a process known as alpha decay. During this process, the alpha particle is emitted from the nucleus of a radioactive atom, traveling at high speeds towards the gold nucleus.
When an alpha particle approaches a gold nucleus, it can either be deflected or absorbed by the gold nucleus. This depends on the energy and trajectory of the alpha particle, as well as the size and composition of the gold nucleus.
Studying alpha particles approaching gold nuclei can provide valuable insights into the structure and properties of atoms and nuclei. It can also help in understanding the behavior of radioactive materials and their potential effects on the environment and human health.
The interaction between an alpha particle and a gold nucleus is related to the strong nuclear force, which is the fundamental force that holds the nucleus of an atom together. This force is responsible for the binding energy that keeps the protons and neutrons in the nucleus from flying apart due to their electrical repulsion.
