Science Spectrum on Instagram: "Here is Explanation The Cavendish Experiment, conducted in 1798 by Henry Cavendish, was designed to measure the gravitational constant (G) and determine the Earth's density. . Using a torsion balance, Cavendish observed the weak gravitational attraction between two lead spheres. This groundbreaking experiment confirmed Newton's law of universal gravitation and was pivotal in understanding gravitational forces. . [Gravitational constant, Torsion balance, Universal
