A 10-cm-long thin glass rod uniformly charged to 12.0 nCnC and a 10-cm-long thin plastic rod uniformly charged to - 12.0 nCnC are placed side by side, 4.40 cmcm apart. What are the electric field strengths E1E_1 to E3E_3 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?
