We have three identical metallic spheres a, b, c. initially sphere a is charged with charge q, while b and c are neutral. first, sphere a is brought into contact with sphere b and then separated from it. after that, sphere a is brought into contact with sphere c and then separated from it. finally, sphere a is brought into contact with sphere b again, and then separated from it
what is final charge of sphere a?

Patricia is trying to compare the average rainfall of new york to that of arizona. a comparison between these two states for the months of july through september would best be measured in

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?
