A plastic rod of length d=1.5 m lies along the x-axis with its midpoint at the origin. The rod carries a uniform linear charge density 2=3.5 nC/m. The point P is located on the postive y-axis at a distance yo=35 cm from the origin. The z-axis points out of the screen. y - dx P X X - Part (b) Choose the correct expression for the y-component of the electric field at P due to a thin slice of the rod of thickness dx located at point .x. - 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 Part (d) Calculate the magnitude of the electric field at point P, in newtons per coulomb.
