Match each of the following experiments with the main result of the experimental work.

Question

BlackTom AI · Accepted Answer

We start by restating the task: Match each of the following experiments with the main result of the experimental work. The options presented are a mix of results and experiment names, so we’ll pair each option with the corresponding famous finding from physics experiments.

Option 1: "Determined the charge of an electron". This result is associated with Millikan’s oil drop experiment, which measured the elementary charge e by balancing gravitational and electric forces on oil droplets. Therefore, this option corresponds to the Oil Drop Experiment, not a direct statement about the oil drop itself as the method; it identifies the outcome (the charge of the electron).

Option 2: "Determined the charge of an electron". This is a repeat of Option 1 with identical meaning. The interpretation remains the same: the result is tied to the Oil Drop Experiment, again not describing a different experiment or a different conclusion.

Option 3: "Determined the charge to mass ratio of electrons". This outcome is classicly linked to J. J. Thomson’s cathode ray tube experiments, which measured the ratio e/m for electrons. In other words, this option maps to the Cathode Ray Tube Experiment as the main result.

Option 4: "Showed that atoms are have a nucleus". The phrasing is a bit awkward, but this result is the famous conclusion from the Gold Foil Experiment conducted by Rutherford, showing that atoms contain a small, dense nucleus. Thus, this option corresponds to the Gold Foil Experiment as the main result.

Option 5: "Gold Foil Experiment". Naming the experiment here, this option points to the specific method that produced the nucleus conclusion. The main result associated with the Gold Foil Experiment is the existence of a nucleus, so this option links the Gold Foil Experiment to the nucleus finding described in Option 4.

Option 6: "Cathode Ray Tube Experiment". This option names the experiment whose main result is the determination of the charge-to-mass ratio of the electron. It directly corresponds to Thomson’s cathode ray work, aligning with the result described in Option 3.

Option 7: "Oil Drop Experiment". This option names the experiment whose key outcome was the measurement of the elementary charge. It maps to the result described in Option 1 (and Option 2), identifying the Oil Drop Experiment as the source of the electron charge value.

If you track the intended pairings, you can see the consistent matches: Gold Foil Experiment -> nucleus result (Option 4 with Option 5), Cathode Ray Tube Experiment -> charge-to-mass ratio result (Option 3 with Option 6), Oil Drop Experiment -> charge of the electron result (Option 1/2 with Option 7).

Note on wording and potential confusion: Some options present the experiment name and others present the final result. When constructing the correct matches, it helps to separate the method (the experiment) from the outcome (the main result). Additionally, the duplicated phrasing of the electron charge (Options 1 and 2) should be treated as the same outcome linked to the Oil Drop Experiment (Option 7).

Match each of the following experiments with the main result of the experimental work.
