At a certain moment, a proton travels from west to east with kinetic energy of 50eV. At this point, the Earth's magnetic field has a horizontal component of 2.0 × (10 ^ −5)T pointing north and a vertical component of 4.8 × (10 ^ −5)T pointing upwards. Initially (before it reaches a region with a significantly different field), what is the trajectory of the proton? What is the radius of curvature of this initial trajectory?

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.
