An electron of mass mmm and charge −e is moving through a uniform magnetic field B→=(Bx,0,0) in vacuum. At the origin, it has velocity v→=(vx,vy,0), where vx>0 and vy>0. A screen is mounted perpendicular to the x axis at a distance D from the origin. *Throughout, you can assume that the effect of gravity is negligible. What is the angular velocity ω of the electron associated with the circular component of its motion?

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.
