Electrons are accelerated from rest in a CRT. These electrons now pass through a magnetic field of 2.70 x 10-2 T and through an electric field of 5.50 x 105 N/C. The fields are perpendicular to each other. If the electrons are not deflected, assuming the electrons are traveling perpendicular to these fields, what is the potential difference across the CRT?

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.
