Easy MCQ +4 / -1 PYQ · JEE Mains 2021

If the Thompson model of the atom was correct, then the result of Rutherford's gold foil experiment would have been :

  1. A All of the $\alpha$-particles pass through the gold foil without decrease in speed.
  2. B $\alpha$-particles are deflected over a wide range of angles.
  3. C All $\alpha$-particles get bounced back by 180$^\circ$
  4. D $\alpha$-particles pass through the gold foil deflected by small angles and with reduced speed. Correct answer

Solution

As in Thompson model, protons are diffused (charge is not centred) $\alpha$-particles deviate by small angles and due to repulsion from protons, their speed decreases.
