A 10-cm-long thin glass rod uniformly charged to 13.0 nCand a 10-cm-long thin plastic rod uniformly charged to -13.nCare placed side by side, 4.30cmapart. What are the electric field strengths E1 to E3 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 in Newtons/Coulomb
