MCQ

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
✓
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

Correct option: C.

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

c
According to Rutherford, $e ^{-}$revolves around nucleus in circular orbit. Thus $e ^{-}$is always accelerating (centripetal acceleration). An accelerating change emits $EM$ radiation and thus $e ^{-}$ should loose energy and finally should collapse in the nucleus.
