A 10-cm-long thin glass rod uniformly charged to 13.0 nC nC anda 10-cm-long thin plastic rod uniformly charged to - 13.0 nC nC areplaced side by side, 4.20 cm cm apart. What are the electric fieldstrengths E 1 E1E_1 to E 3 E3E_3 at distances 1.0 cm, 2.0 cm, and3.0 cm from the glass rod along the line connecting the midpointsof the two rods? Specify the electric field strength of E1, E2,E3?
