Two large metal plates are seperated by 0.15m. The upper plate caries positive charge and lower plate carries negative charge with the same magnitude, so there is a uniform electric field between the plates with magnitude 500V/m. A small particle with positive charge q= +8.0x10-4 C enters midway between the plateds with speed of v=700m/s. The magnetic field in the region between the plates is uniform and is going into the page. What are the magnitude and direction of the magnetic field that enables the particle to pass between the plates with no deflection.

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.
