Gravitational Constant Instrument for teaching
1. General
The Instrument is of a small sized experimental instrument
based on Cavendish torsion balance which is used to test and
verify the constant of universal gravitation. The Instrument can
be used to observe qualitatively the phenomenon of universal
gravitation between objects, to measure quantitatively the
constant G and to prove F∝1/r2. The Instrument can be used in experiment for students due to its apparent demonstrational
effect.
