Two resistanceless rails rest 42 cm apart on a 6.6o ramp. They are joined at the bottom by a 0.68 Ω resistor. At the top, a copper bar of mass 0.034 kg (ignore its resistance) is laid across the rails. The whole apparatus is immersed in a vertical 0.35 T field. What is the terminal (steady) velocity of the bar as it slides frictionlessly down the rails?

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.
