An electron starts from rest near the negative vertical plate of a set of parallel plates and accelerates towards the positive plate through 150 V. After crossing this distance the electron passes through a hole. The electron then moves through a horizontal set of parallel plates where the top plate is negative. These horizontal plates are separated by 2.0 cm and have a potential difference of 240 V. The electron passes through these plates undeflected due to a magnetic field perpendicular to the page. The electron then passes out of the plates where it is acted upon by the same uniform magnetic field. Find the magnitude and direction of the uniform magnetic field and the radius of the circular path of the electron. Draw the complete path of the electron.

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.
