How Do I Calculate Coulomb's Law for Fractional Electrical Charges?

AI Thread Summary
To calculate Coulomb's Law for fractional electrical charges, the fractional value can be directly used in the formula F = K * (qa * qb / r^2). If the charge is +2/3, it should be plugged in as 2/3 in the q's spot. The unit of charge is Coulombs, and for two charges of +2/3 C, the calculation would be F = (8.98e9)(2/3)^2 / r^2. Understanding the relationship between fractional charges and their representation in Coulombs is crucial for accurate calculations.

The law I am talking about is F=K* (qa*qb / r2) I know the values of all but I have a question on the q's which represent the electrical charges...
If the charge is +2/3 do I plug in the fraction 2/3 in the q's spot? is this the numerical number I use? PLEASE HELP!

Are you trying to find the coulomb force between two charges of +2e/3?

OK, so what unit is charge measured in? How much is e in those units? So how much then is 2/3e?

If both of the charges are +2/3 C, then you just plug in the charges for q

F = KQQ / R^2
F = (8.98e9)(2/3)^2 / R^2

The units for charge are Coulombs.

Thread 'Inducing EMF Through a Coil: Understanding Flux'

Thank you for reading my post. I can understand why a change in magnetic flux through a conducting surface would induce an emf, but how does this work when inducing an emf through a coil? How does the flux through the empty space between the wires have an effect on the electrons in the wire itself? In the image below is a coil with a magnetic field going through the space between the wires but not necessarily through the wires themselves. Thank you.

Thread 'Griffith, Electrodynamics, 4th Edition, Example 4.8. (Second part)'

I am reading the Griffith, Electrodynamics book, 4th edition, Example 4.8. I want to understand some issues more correctly. It's a little bit difficult to understand now. > Example 4.8. Suppose the entire region below the plane ##z=0## in Fig. 4.28 is filled with uniform linear dielectric material of susceptibility ##\chi_e##. Calculate the force on a point charge ##q## situated a distance ##d## above the origin. In the page 196, in the first paragraph, the author argues as follows ...
