A charge travels from the positive terminal of a 6�-V battery, through a light bulb, and through the battery back to the positive terminal. The total change in voltage experienced by the charge during this journey is

A) -1V
B)1V
C)-6V
D)6V
E)0V

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?
