The thin plastic rod of length L=16.8 cm in the figure has a nonuniform linear charge density Acx, where c = 45.8 pC/m. (a) With V-0 at infinity, find the electric potential at point P₂ on the y axis at y-D=5.83 cm. (b) Find the electric field component E, at P₂ (a) Number (b) Number i 0.0613 --- Units D Units V

We will first write expression for electric potential and electric field due to a point charge. We then use them to find electric potential and electric field at point P₂ due to a small charge element of rod. We then integrate these expressions to find the electric potential and electric field due to entire charge of rod. The detailed steps are as follows.
