Imagine two opposite flowing current sheets +k(t)amps/meter and -k(t)amps/meter, both flowing in the x-direction. the two current sheets are located at yi-h/2 and ½ they are separated bv a distance h along the y -direction. a positive charge q is placed at y = h > h/2 above the top plate. the currents slowly increase from k(t =-oo) 0. (a) calculate the induced electric field everywhere in space under a quasi-static approximation (b) calculate the momentum transferred to the point charge after the currents have reached their terminal values of k(t - +oo) - ko (c) derive the conditions under which the quasi-static approximation is valid
