In this problem we want to calculate the electric field due toseveral charge linear distributions .a) Consider a thin rod oflength L. The rod carries a uniform charge density, λ, and totalcharge Q. Calculate the electric field at a point p that is on therod’s cylindrical axis of symmetry and a distance d away from theend of the rod. Do this by direct integration. How does yourexpression be have as L→∞?b) Repeat, with the rod’s charge densitybeing λ=αx, whereαhas a numerical value of 0.25 (what are thedimensions and units of α?)?
