2 In the Bohr model of the hydrogen atom, the speed of the electron is
3 approximately $v = 2.20\E{6} \U{m/s}$. Find \Part{a} the force acting
4 on the electron as it revolves in a circular orbit of radius $r =
5 0.530\E{-10} \U{m}$ and \Part{b} the centripetal acceleration of the
7 \end{problem*} % problem 5.16
13 = \frac{(2.20\E{6}\U{m/s})^2}{0.530\E{-10}\U{m}} \\
14 = \ans{9.13\E{22}\U{m/s}^2}
17 And going back to \Part{a}, (where the mass of an electron $m_e =
18 9.109\E{-31} \U{kg}$ came from the inside front cover of the text.)
21 = 9.109\E{-31}\U{kg} \cdot 9.13\E{22}\U{m/s}^2
22 = \ans{8.32\E{-8}\U{N}}
