Choose the correct option from the following options given below :
(a) In the ground state of Rutherfords model electrons are in stable equilibrium. While in Thomsons model electrons always experience a net-force.
(b) An atom has a nearly continuous mass distribution in a Rutherfords model but has a highly non-uniform mass distribution in Thomsons model
(c) A classical atom based on Rutherfords model is doomed to collapse.
(d) The positively charged part of the atom possesses most of the mass in Rutherfords model but not in Thomsons model.
