A straight rod of length L = 22.2 cm, carries a uniform charge, ? = 3.00 × 10-6 C/m. The rod is located along the y-axis from y1 = 0.00 to y2 = L. Find the expression for the electric field along the y-axis, Ey, at a point P. What is the magnitude of the electric field at yP = 50.0 cm? (will rate you for a correct answer with work)
