प्रश्न
Draw a graph showing the variation of the number of particles scattered (N) with the scattering angle θ in the Geiger-Marsden experiment. Why only a small fraction of the particles are scattered at θ > 90°?
उत्तर
Graph showing the variation of the number of particles scattered (N) with the scattering angle (θ):
The strongly repulsive force exerted by the positively charged nucleus causes the scattering of α-particles at θ > 90°. Because the nucleus is so small, there are fewer distributed α-particles.
