Question 2

Classical theory predicts that the planets can orbit the Sun quite stably.
 
  Why could not stable orbits be predicted for the atom by simply substituting the electrical attraction for the gravitational attraction? Why was there a classical crisis in describing the atom?

Answer to Question 1

B

Answer to Question 2
