When did Henry Cavendish report the measurement of the gravitational constant with the mass and density of the Earth?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2, i.e. June 1798
- Henry Cavendish reported the measurement of the gravitational constant with the mass and density of the Earth in the year 1798. This significant experiment, known as the Cavendish experiment, allowed him to estimate the density of the Earth and determine the gravitational constant, which is a crucial parameter in Newton's law of universal gravitation.
