  • Electron in circular motion?! Please help me someone! :(?

    An electron has a kinetic energy of 2.05E-17 J. It moves on a circular path that is perpendicular to a uniform magnetic field of magnitude 5.35E-5 T. Determine the radius of the path.

  • Number of free electrons per volume in Copper and Aluminium?

    It seems that, as Copper only looses 1 electron and Aluminium looses 3, that Al should be more conductive? This, however, is not true! Why?!
