Discuss the limitation of Bohr's theory on the basis of Heisenberg's uncertainty principle.

  ⇛According to Bhor's theory negatively charged particles(electrons) inside an atom revolve around the nucleus in well defined orbits having fixed radius. In order to balance the nuclear attractive force electron must move with a definite velocity. But according to uncertainty principle it is impossible to determine simultaneously the exact position and momentum of a microscopic particle like electron. Thus Bohr's model contradicts Heisenberg's uncertainty principle...
