Q35 · Physics
In Geiger-Marsden experiment, the number of scattered -particles is plotted as a function of scattering angle . Which of the following options represents the correct plot ?
The figure, described in words
Options are plots of N(theta) on a log scale (10 to 10^7) vs scattering angle 0-180 degrees.
- 1[plot: N(theta) increasing steadily (straight line on log scale) from 0 to 180 degrees]
- 2[plot: N(theta) flat near 10^7 up to about 60 degrees, then decreasing towards 180 degrees]
- 3[plot: N(theta) very large at small angles, falling steeply and levelling off at large angles]Official answer
- 4[plot: N(theta) bell-shaped, peaking around 90 degrees]
Official answer: option 3 · NTA final answer key
