JEE Mains · Physics · STD 12 - 12. atoms
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 & Solution
Correct Answer
(C) A classical atom based on Rutherford's model is doomed to collapse.
Step-by-step Solution
Detailed explanation
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.
