Step 2: Span the charge distribution

Previous Step / Next Step

[line of charge]

Assuming a uniform charge distribution along a line, the variable which appears to be the easiest to use to span the distribution is the variable x, which follows along the line from negative infinity to positive infinity. Thus the charge infinitesminal dq will be the product of charge density and dx.
