Q:
A uniform line charge that has a linear charge density λ = 4.4 nC/m is on the x-axis between x = 0 to x = 5.0 m.
(a) What is its total charge?
(b) Find the electric field on the x-axis at x = 6 m.
(c) Find the electric field on the x-axis at x = 11.0 m.
(d) Find the electric field on the x-axis at x = 240 m.
To solve for a, I used the equation Q=lambda*length. My answer is 22nC, which is correct.
To solve for the remaining portion of the question, I used E=kQ/[x^2], where I took x to be (L+a-x). L is defined as the length of the rod (5m), a is the difference between the given position and the rod (for b, 1m), and x is the distance from the origin to the midpoint of the rod (2.5m).
