Gravitational Balance SN1035


Exp-1 Determining of G, the fundamental gravitational Constant.
Exp-2 Verifying the inverse-square law.

Principle and Working:
This instrument allows measuring G with a high precision (with a maximum error of 15%). In the initial displacement method, G is derived from the angular acceleration of the balance due to movement of the attracting masses from one side to the other. The equilibrium displacement method derives G from the change in the equilibrium position of the balance at rest due to the change in position of the large masses. The built-in oil damping system reduces the time needed for equilibrium.
