-
A.
oil-drop experiment
chosen
The oil-drop experiment was a landmark early 20th-century physics experiment that measured the elementary electric charge of the electron by observing tiny charged oil droplets suspended in an electric field.
-
B.
Franck–Hertz experiment
The Franck–Hertz experiment is a landmark early-20th-century physics experiment that provided direct evidence for the quantization of atomic energy levels, supporting the Bohr model of the atom.
-
C.
Cockcroft–Walton experiment
The Cockcroft–Walton experiment was a pioneering 1932 nuclear physics experiment that achieved the first artificial disintegration of atomic nuclei using accelerated protons, confirming Einstein’s mass–energy equivalence.
-
D.
Trouton–Noble experiment
The Trouton–Noble experiment was an early 20th-century test of the luminiferous aether that searched for a torque on a charged capacitor in motion and, by finding no such effect, provided support for the emerging theory of special relativity.
-
E.
Cavendish experiment
The Cavendish experiment was an 18th-century physics experiment by Henry Cavendish that measured the tiny gravitational attraction between lead spheres, allowing the first calculation of the gravitational constant and the mass of the Earth.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
