A +40 positively-charged metal sphere (Sphere A) and an electrically-neutral metal sphere (Sphere B) are sitting on insulated stands on a table. The two spheres are brought into contact with eac other, and then the contact is broken. Using conservation of charge, which statement describes the movement of charges between the two spheres?

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?
