I'm not sure if that was a rhetorical question to get me thinking, but dr⃗ is intended to be radially outward from the line charge. I'm not sure how I would use the superposition principal here for a point charge... frogjg, so in that case with the indefinite integral, my answer should...

Homework Statement For the single line charge, derive an expression for Electric Potential. Homework Equations V(r)=-\intE\bulletdr E for infinite line = \frac{\lambda}{2\pi r\epsilon} The Attempt at a Solution The integration is straightforward enough—my question is as to what the...

I need to build a completely horizontal projectile launcher for my physics class. I started experimenting with a Gauss rifle, but the horizontal velocity was hardly even 1m/s, even with strong magnets. I'm looking into a few other propulsion mechanisms, such as pressurized air (like a spud gun)...
