A 10-cm-long thin glass rod uniformly charged to 11.0 and a 10-cm-long thin plastic rod uniformly charged to - 11.0 are placed side by side, 3.60 apart. What are the electric field strengths to at distances 1.0 cm, 2.0 cm, and 3.0 cm from the glass rod along the line connecting the midpoints of the two rods? Specify the electric field strength E1, E2, and E3
