A hydrogen atom (with the Bohr radius of half an angstrom) is situated between two metal plates 1 mm apart, which are connected to opposite terminals of a 500 V battery. What fraction of the atomic radius does the separation distance d amount to, roughly? Estimate the voltage you would need with this apparatus to ionize the atom.
d) Show that the resistivity canbe expressed (via the familiar notation) as, m p= net here m is the electronmass; † is the period of time that elapses between two subsequent collisions, the electron undergoes with copper nuclei throughout its chaotic motion in the body of copper (supposing that the current carrying cable is made of copper). Hint: Write F=eE, i.e. the electric force reigning on the electron. Write also the acceleration a=F/m, an electron is subject to, based on the Newton's law ofmotion.
