Chapter 38: Problem 4

Which of the following can be used to explain why you can't walk through walls? a) Coulomb repulsion d) the Pauli exclusion b) the strong nuclear force \(\quad\) principle c) gravity e) none of the above

Short Answer

Expert verified
a) Coulomb Repulsion b) Strong Nuclear Force c) Gravity d) Pauli Exclusion Principle Answer: d) Pauli Exclusion Principle

Step by step solution

01

Understand Coulomb Repulsion

Coulomb repulsion is the repulsive force between two particles with the same electric charge. It plays a role in determining the behavior of charged particles but does not directly explain why one cannot walk through walls.
02

Understand Pauli Exclusion Principle

The Pauli exclusion principle states that two identical fermions (such as electrons) cannot simultaneously occupy the same quantum state in a quantum system. This principle applies to the behavior of electrons in atoms and is responsible for the stability of matter.
03

Understand Strong Nuclear Force

The strong nuclear force is one of the fundamental forces in nature responsible for binding together protons and neutrons within atomic nuclei. This force acts at very short ranges and is not relevant for the interaction between a person and a wall.
04

Understand Gravity

Gravity is the fundamental force that exists between any two objects with mass, causing them to be attracted towards each other. However, gravity mainly affects large-scale objects like planets and does not directly explain why a person can't walk through walls.
05

Choose the correct answer

Based on the explanations provided in Steps 1-4, "the Pauli exclusion principle" (option d) is the correct answer as it is responsible for the stability of matter, which prevents a person from walking through walls.

The muon has the same charge as an electron but a mass that is 207 times greater. The negatively charged muon can bind to a proton to form a new type of hydrogen atom. How does the binding energy \(E_{\mathrm{B} \mu}\) of the muon in the ground state of a muonic hydrogen atom compare with the binding energy \(E_{\mathrm{Be}}\) of an electron in the ground state of a conventional hydrogen atom? a) \(\left|E_{\mathrm{B} \mu}\right| \approx\left|E_{\mathrm{Be}}\right|\) d) \(\left|E_{\mathrm{B} \mu}\right| \approx 200 \mid E_{\mathrm{Be}}\) b) \(\left|E_{\mathrm{B} \mu}\right| \approx 100\left|E_{\mathrm{Be}}\right|\) e) \(\left|E_{\mathrm{B} \mu}\right| \approx\left|E_{\mathrm{Be}}\right| / 200\) c) \(\left|E_{\mathrm{B} \mu}\right| \approx\left|E_{\mathrm{Be}}\right| / 100\)
