Easy MCQ +4 / -1 PYQ · JEE Mains 2022

Choose the correct option from the following options given below :

  1. A In the ground state of Rutherford's model electrons are in stable equilibrium. While in Thomson's model electrons always experience a net-force.
  2. B An atom has a nearly continuous mass distribution in a Rutherford's model but has a highly non-uniform mass distribution in Thomson's model.
  3. C A classical atom based on Rutherford's model is doomed to collapse. Correct answer
  4. D The positively charged part of the atom possesses most of the mass in Rutherford's model but not in Thomson's model.

Solution

<p>An atom based on classical theory of Rutherford's model should collapse as the electrons in continuous circular motion that is a continuously accelerated charge should emit EM waves and so should lose energy. These electrons losing energy should soon fall into heavy nucleus collapsing the whole atom.</p>
