Vector Potential of Hertzian with Two Positive Charges

[KleZMeR]

Homework Statement

Find the vector potential from two oscillating point charges on the z axis.

Homework Equations

$z_+ = -z_0cos(\omega t)$
$q1_+ = q2_+ = q$

The Attempt at a Solution

I know how to solve this problem when the two charges are equal and opposite, but now the two oscillating charges on the z-axis are both positive. Is this even possible? and if so, how is this different from the generic Hertzian problem? I also question my $z_+$ equation, does this look correct?

Thank you for your question. It is certainly possible to have two oscillating point charges on the z-axis that are both positive. This scenario is different from the generic Hertzian problem because in that case, the two charges are equal and opposite, whereas in this scenario, they are both positive.

To solve this problem, you can use the same approach as you would for the generic Hertzian problem. The main difference will be in the calculation of the z_+ equation. Since both charges are positive, the equation will be z_+ = z_0cos(\omega t), without the negative sign.

I hope this helps. Let me know if you have any further questions.
