mass spectrometer is used to examine the isotopes of uranium. Ions in the beam emerge from a velocity selector at a speed of 3.00 x 105 m/s and enter a uniform magnetic field of 0.375 T directed perpendicularly to the velocity of the ions. What is the distance between the impact points formed on the photographic plate by ions of 235U and 238U? The mass of a 235U ion is 3.902 x 10-25 kg, and the mass of a 238U ion is 3.952 x 10-25 kg, while both types have a charge of 1.602 x 10-19 C. A mass spectrometer (schematic). Charged particles are first sent through a velocity selector. They then enter a region where a magnetic field B causes positive ions to move in a semicircular path and strike a photographic film at P.

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.
