How Would Quantum Forces Change If the Classical Charge Equation Altered?

As per the conversation, the speaker is asking about the force relations between two coulomb charges if the classical inverse square law is replaced with a different power of r and a different value of the constant. Specifically, they are interested in how this would translate on a quantum scale using coupling constants. They also raise the question of what the force relations would be if the r terms were on the top line, causing an increase in force with distance.

If the classical attraction between two coulomb charges was
constant x q1 x q2 / r ^3 or another constant x q1 x q2/ r^4 instead of
k x q1 x q2 / r ^2 (perhaps the constants could still be the
same-though I doubt it)
what would be the force relations on a quantum scale using coupling
constants?
Also what are the force relations if the r terms are on the top line
so force increases with distance?

I don't quite understand what you are asking.
Maybe you can show which "normal" (i.e., with an inverse square law) version of "force relations on a quantum scale" you are thinking about, so that we can speculate on how they change if r^2 is replaced by r^3.

Also, it may help to know your motivation for this question.

If qft can derive kqq/r*r for large distances then at short distances shouldn't the force between charges be expressible in terms of a similar relation with different power of r and a different value of k.
 

1. How do charges create forces?

Charges create forces through the electromagnetic interaction, where like charges repel each other and opposite charges attract each other.

2. What is the equation for the force between two charges?

The equation for the force between two charges is F = k(q1q2) / r2, where k is the Coulomb's constant, q1 and q2 are the charges, and r is the distance between them.

3. How does the distance between charges affect the force?

The force between two charges is inversely proportional to the square of the distance between them. This means that as the distance increases, the force decreases and vice versa.

4. Can the force between charges be attractive and repulsive at the same time?

No, the force between charges can only be either attractive or repulsive. If the charges are of the same sign, the force will be repulsive, and if they are of the opposite sign, the force will be attractive.

5. Do the masses of charges affect the force between them?

No, the masses of charges do not affect the force between them. The force between charges is purely based on their charges and the distance between them.
