Problem A12: Consider the long thin semi-infinite non-conducting rod shown in the figure above. It lies on the x-axis with the left end located a distance n₂d from the origin. The linear charge density of the rod decreases as 1/x^n₁ where x is the distance from the origin. The expression for the linear charge density is &lambda = C/x^n₁, where C is a constant. What is the magnitude of the electric field at the origin? That is if |E| = (1/n₃) kC/d^n₁+1, what is n₃?
