1. The problem statement, all variables and given/known data A uniform line charge extends from x = - 2.7 cm to x = + 2.7 cm and has a linear charge density of lambda = 6.5 nC/m. (a) Find the total charge. Find the electric field on the y axis at the following distances. (b) y = 4 cm 2. The attempt at a solution It was easy to find the charge... Q = 6.5 nC/m * 0.054 m = 3.51nC*10e-1 ..I'm having issues with how to approach the second part, I dont know whether to use an equation, I'm not even sure which equation to use, I know I need to use Coulomb's Law but I don't know how to use it. Thanks for the help in advance!!
