In the Geiger-Marsden experiment,which of the following is used to calculate the trajectory of the $\alpha$-particle?

Describe the Geiger-Marsden scattering experiment.

In the Rutherford experiment,$\alpha$-particles are scattered as shown in the figure. Which of the four paths is not possible?

In the Rutherford's nuclear model of the atom,the nucleus (radius about $10^{-15} \; m$) is analogous to the sun about which the electron moves in an orbit (radius $\approx 10^{-10} \; m$) like the earth orbits around the sun. If the dimensions of the solar system had the same proportions as those of the atom,would the earth be closer to or farther away from the sun than it actually is? The radius of the earth's orbit is about $1.5 \times 10^{11} \; m$. The radius of the sun is taken as $7 \times 10^{8} \; m$.

Based on which experiment did the Rutherford nuclear model come from?

What is the impact parameter?
