Are you trying to find the coulomb force between two charges of +2e/3?robertroman10 said: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!

To calculate Coulomb's law, you use the formula F = (k * q1 * q2) / r^2, where F is the force between two charged objects, k is the Coulomb's constant, q1 and q2 are the charges of the two objects, and r is the distance between them.
The value of Coulomb's constant, denoted by k, is 8.99 x 10^9 Nm^2/C^2. It is a fundamental constant in electrostatics and is used to calculate the force between two charged objects.
Coulomb's law uses the SI units of Newtons (N) for force, meters (m) for distance, and Coulombs (C) for electric charge. The value of Coulomb's constant is also expressed in these units.
As distance increases between two charged objects, the force between them decreases. This is because the inverse square relationship in the formula (F = 1/r^2) means that the force decreases exponentially as distance increases.
Yes, Coulomb's law can be used for both positive and negative charges. The direction of the force will depend on the types of charges (positive-positive, negative-negative, or positive-negative) and the direction of the force will be along the line connecting the two charges.
