(13%) Problem 5: A plastic rod of length d = 4.5 m lies along the x-axis with its midpoint at the y origin. The rod carries a uniform linear charge density 4 - 7.5 nC/m. The point P is located on the postive y-axis at a distance vo - 15 cm from the origin. The z-axis points out of the screen X Otheexp -25% Part (a) By symmetry the electric field at point P has no component in the x and = directions Correct! " 25% Part (b) Choose the correct expression for the y-component of the electric field at P due thin slice of the rod of thickness dx located at point x. Correct! 25% Part (c) Integrate your correct choice in part (b) over the length of the rod and choose the correct expression for the y-component of the electric field at point P. Correct! p a 25% Part (d) Calculate the magnitude of the electric field at point P, in newtons per coulomb.
