Find the probability current density for a 1-dimensional plane wave function of the form ψ(x, t)-ae*(p-e) where e-p2/2m. 5) use the result from problem (4) to explicitly evaluate all of the wavefunction parameters (a, p, e) for a beam of electrons moving along the + x-direction with a current of 1 ma and an energy of 2 kev

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?
