Rutherford discovered the nucleus of the atom by firing a particles at gold foil. an a particle has a charge of q = +2e and a mass of m = 6.64-10-27 kg. a gold nucleus has charge of q-+79e. you may ignore the motion of the gold nucleus in this problem +2e +79e suppose an α particles is traveling directly toward a gold nucleus. if the speed of the a particle is u = 1.9. 107 m/s when it is 1 m from the gold nucleus, how close to the gold nucleus will the a particle come before it stops and reverses direction?
Answers: 3
kg
![\frac{1}{2}\left ( 6.64\times 10^{-27}\right )\left ( 1.9\times 10^{7}^2\right )=\frac{9\times 10^9\times 158\times \left ( 1.6\times 10^{-19}\right )}{y}\left [\frac{1}{r_0}-\frac{1}{1}\right ]](/tpl/images/0136/9935/07d6a.png)
