Arectangular parallelipiped "wire" of length 1.3m , height 5.8×10−2m , and depth 2.6×10−2m lays with its end faces parallel to the xy -plane. the depth runs parallel to the x -axis and the height runs parallel to the y -axis. the centers of the end faces coincide with the z -axis. a constant potential difference of 340v is maintained between the two end faces. as it turns out, the density of current running along the length of the wire depends on position like j(rx, ry)= 54a/m6 r2xr2y . what is the magnitude of the current density at the corner of the wire that sits in the first quadrant?
