Magnetic Field Of Coaxial Cable

The word coaxial means same axis. So for a long straight cable to be coaxial, it must have concentric cylindrical shaped conductor around it. Coaxial cable (popularly called ‘coax’) has various applications ranging from current conductors to radiofrequency signal transmitters. This cable has lower emission losses and provides protection from electromagnetic interference which allows signals with less power to transmit over longer distances.For example, currents produced in the pickup of a stereo turntable generally travel to the amplifier through a coaxial cable.The self-inductance of a coaxial cable is another important characteristic, because it influences the propagation of electrical signals in the cable.

Question

In the figure, an electron with an initial kinetic energy of 4.40 keV enters region 1 at time t = 0. That region contains a uniform magnetic
field directed into the page, with magnitude 0.0120 T. The electron goes through a half-circle and then exits region 1, headed toward
region 2 across a gap of 25.0 cm. There is an electric potential difference AV = 2000 V across the gap, with a polarity such that the
electron's speed increases uniformly as it traverses the gap. Region 2 contains a uniform magnetic field directed out of the page, with
magnitude 0.0206 T. The electron goes through a half-circle and then leaves region 2. At what time t does it leave?
