You need not have a technique for finding the arbitrary form of the constant, and you may use anything in the heading of this exam. Explain a good technique for determining without memorization how to determine the constant in Gauss's Law. You may assume that you know Coulomb's Law. In the Bohr model of the hydrogen atom, an electron circles a proton at a radius of a . A thin cylindrical shell of radius R is 1 surrounded by a second concentric concentric cylindrical shell of radius R .
L is placed a distance b to the right of the origin.
Note that a occurs in two different places in this problem.
