OK, thank you for the replies they give some new ways to think about the problem.

So we're currently covering multipole expansion techniques in my EDM class. The multipole expansion is a summation of integrals each treating a different configuration of discrete charges (monopole, dipole... and so on). The term in the summation that corresponds to the physical configuration...

Ok, that makes the problem a lot more straight forward. Thanks for bearing with me and your insightful input.

A and B are equidistant from C, sorry I forgot to mention this in the previous post.

All the particles are moving in the positive x direction. C is in between A and B, with behind and B in front. A and B will arrive at C's position simultaneously.

Homework Statement There are three particles along the x-axis ordered from back to front, A, C, B. A travels at 4/5c and B travels at 3/5c, the speed of particle C is unknown. What must the speed of particle C be such that A and B will arrive at C at the same time? And, at what speed will both...
