Choose the correct option from the following options given below :
Select the correct option:
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.

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