A 10-cm-long thin glass rod uniformly charged to 10.0 nCnC and a 10-cm-long thin plastic rod uniformly charged to - 10.0 nCnC are placed side by side, 4.00 cmcm apart. What are the electric field strengths E1E1E_1 to E3E3E_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

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?
