LC-5 A line of length L with constant linear charge density +(C/m) lies on the x axis. A point P lies on the perpendicular bisector of the line (the y axis). a) Show the details of the symmetry argument (pick dq's and show their dE's) to explain which of the two components (x or y) of the net field at point P are equal to zero due to the entire line of charge. Use the figure in your explanation. Explicitly state which variables must be equal. +2 a X b) Apply Coulomb's Law, E=K, to find the net E due to the entire line of charge at point P. Kq Get this answer in terms of only the symbols K, L, a, λ (not in terms of any angle).
