1. The problem statement, all variables and given/known data A point exists a distance D away from a rod of length L ( (point) |-----d-----| (ROD) ) So the point is in allignment with the rod, charged with a uniform charge density of -6.5uC/m 2. Relevant equations E= Integral(k(dq/r^2) 3. The attempt at a solution Im not asking for help on finding the answer, i just want to understand a bit more about charge density. It says that it is (-), in short, does that mean that the rod has a negative charge? meaning that the point (positive ) will be attracted to the rod? Thanks. One more thing, is the radius (r) the distance from the point to the center of the rod?
