Question

Consider Rutherford’s gold foil experiment. If the energy of the  particles used is increased, what would happen to their paths?A)The particles are more likely to collide with the nuclei with a greater impact, causing them to deflect less – therefore fewer particles would be found further away from the center.B)The particles are more likely to collide with the nuclei with a greater impact, causing a greater number of deflections – thus the intensity of the "spots" will increase.C)Their paths would be identical to those of  particles with lower energies. D)The observed pattern of α particle deflection will remain the same, but the intensity of the "spots" observed will decrease.E)The particles are more likely to collide with the nuclei with a greater impact, causing them to deflect more (that is, a greater number will be found away from the center).

Answer 1

Answer: Option C - Their paths would be identical to those of α-particles with lower energies.

Step-by-step explanation:

Note that the PATHS TRAVELLED and deflection observed in the Rutherford gold foil experiment was based on ELECTRIC CHARGE carried by the individual particles NOT energy levels.

So, even after increasing the energy levels, their paths would be identical to those of α-particles with lower energies.
