Cavendish Gravitational Balance

Product Code : EL-PLE-13144Eduscope India is a leading Cavendish Gravitational Balance Quick Answer: Cavendish Gravitational Balancemeasures the Universal Gravitational Constant, G, and demonstrates the gravitational attraction between masses on a benchtop.

The apparatus is based on the design first used by Henry Cavendish in 1798 to measure the density of the Earth, from which G can in turn be derived — one of the most famous experiments in the history of physics, sometimes called "weighing the Earth." This version is precisely constructed and substantially less expensive than earlier models, allowing measurements of G to better than 15% relative error using either of two methods: the initial acceleration method, which measures the initial rate of angular acceleration as a large mass is brought close to the torsion balance, or the equilibrium displacement method, which lets the balance settle fully and measures its final angular displacement. Because gravity is by far the weakest of the four fundamental forces, detecting and quantifying it directly gives students a rare, hands-on physics instruments supplier India experience with one of physics' most elusive interactions, and the same setup can also be used to verify the Inverse Square Law for gravitational forces.

It is part of EduScope India'sPhysics Lab Equipmentrange, and pairs naturally with theFoucault's Pendulum Apparatusfor a broader set of hands-on demonstrations of otherwise abstract physics phenomena.
