Ahh yes of course, I'm starting to get the idea behind what you're saying. It actually makes a lot of sense that dx and dq will always follow the charge density Q/L. This really helped me to understand the idea better, I really appreciate the help Simon, thanks so much

I understand what you're saying with this. We know that x (variable) is changing. It is reaching from the point of interest to an arbitrary point on the line charge. This means that x could be any length. Is dx then always a specified amount (infinitesimal in size) or is it a ratio of the...

Thanks for the response, but I'm still a bit confused about why these ratios are equal. It makes sense that we need to find the change that occurs between charge Q and distance X, but I don't know why that would be equal to Q/L. The proportion of X that dX is does not seem to be the same as that...

Hi guys, first time posting here, but I have a question that I have been thinking about for quite a while, and I hope someone can help out with it. Assume a line of charge (with overall charge of +Q and of length L) that is lying on the x-axis. You want to calculate the electric field strength...
