| Summary: | "The Newtonian constant of gravitation is determined by measuring the gravitational force of attraction between massive spheres of lead and mercury. A torsion balance is used to measure the deflection angle which balances the torsional couple of the balance with the gravitational couple exerted by the massive spheres. Students record clockwise and counterclockwise deflections of the balance."--Container. |
