A thin rod of length L and uniform charge per unit length À lies along the x-axis with its center at the origin as shown in the figure below. y d P Bo -X O T -L- a. Show that the electric field at point P located a distance d from the rod has no x-component and has a magnitude equal to E = 2k Asin(80)/d. b. Use the previous result to show that if the rod has an infinite length, that its electric field has a magnitude equal to E = 2k ^/d.
