An insulating rod of length 2a is aligned along the y-axis and centered on the x-axis. If the rod has a linear charge density given by Lambda(y) = 3Q/4a3(a2-y2) for -a to a
a) Find the electric potential at point p on the x-axis outside the rod. PLEASE show steps, wont rate if there is none..last guy didnt
b) Use the potential energy function found in part a to determine the electric field along the x-axis.
