Consider a line of charge that extends along the x-axis from x = -1.3 m to x = +1.3 m.  The line of charge has a nonlinear charge density given by ?λ(x) = 7.7 |x|  (nC/m).  (Note: that is the absolute value of x.)  Calculate the electric potential on the y-axis at y = 4.2 m, in V.  Use k = 9 x 109 N m2 / C2.  (Hint: Calculate the potential of the right half of the charge distribution and multiply by 2.)
