1. The problem statement, all variables and given/known data A sheet of charge Ps = 2 NC/m^2 is present at the plane x = 3 in free space, and a line charge Pl = 20 nC/m is located at x = 1, z = 4. a) Find the magnitude of the electric field intensity at the origin b) Find the direction of E at P (4,5,6) c) What is the force per meter length on the line charge? 2. Relevant equations Field of a sheet of Charge E = Ps/2(epsilon) * An 3. The attempt at a solution At the origin, do I just use the equation above? For the direction to (4,5,6), how exactly would I draw the vectors? Appreciate the help, thanks!
