Athin wire oriented along the x-axis carries a current i in the +x direction. at a certain instant, a point charge +q is coincident with the point (x, y, z)= (0, a, 0) and moves with velocity v= v 3 [2ˆx+2ˆy−zˆ]. what is the vector force f on the charge at that instant, in terms of i, q, v, a, and fundamental constants?

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?
