Question

Choose the correct option from the following options given below :

• 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
• 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
• C. A classical atom based on Rutherford’s model is doomed to collapse.
• D. The positively charged part of the atom possesses most of the mass in Rutherford’s model but not in Thomson’s model.

Answer 1

Answer: (C)

A classical atom based on Rutherford’s model is doomed to collapse.

Answer 2

An atom based on classical theory of Rutherford’s model should collapse as the electrons in a 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 a heavy nucleus collapsing the whole atom.
The correct option is (C) : A classical atom based on Rutherford’s model is doomed to collapse.
