A continuous charge distribution shown in Fig. 2 is a straight thin rod of length 4a the middle half of which is charged with the uniform line charge density $+\lambda > 0$ and two end parts with the uniform charge density $-\lambda < 0$. What is the direction of the electric field E produced by this charge distribution at point P at distance r from the center of the 1 rod? What is the electric field magnitude E(r) as an exact function of distance r? As you know, in the limiting cases E(r) can exhibit a power-law dependence $E(r) \propto 1/r^n$ on distance r. Either analytically or numerically assess the exact result you derived for arbitrary r and deduce the power-law exponents n for two limiting cases: (a) when point P is very close to the rod ($r \ll a$) and (b) when point P is very far from the rod ($r \gg a$).

1. Consider the function $f: \{1,2,3,4\} \to \{a,b,c\}$ given by $f(1) = b$, $f(2) = c$, $f(3) = b$, $f(4) = a$ and the function $g: \{a,b,c\} \to \{1,2,3,4\}$ given by $g(a) = 4$, $g(b) = 3$, $g(c) = 2$. Is $g$ the inverse of $f$? Why or why not?
