Question

dear friend

explain:---- gravitational constant ( Cavendish's experiment ) in physics....​

Answer 1

Answer:

The Cavendish Experiment is a clever way to measure the Gravitational Constant that is stated in the Universal Gravitation Equation. ... This experiment used a torsion balance device to attract lead balls together, measuring the torque on a wire and equating it to the gravitational force between the balls

Answer 2

Answer:

your answer

Explanation:

the value of the gravitational constant G was first determined experimentally by English scientists Henry Cavendish's in 1798.

two small lead sphere of mass m each are connected to the end of a rod of length L which is suspended from it's mid point by a fine quartz fibre, forming a torsion balance.

two large lead sphere of mass m each are brought close to small ones but on opposite sides.

as, the small sphere move towards the larger ones under the gravitational attraction. thus , the gravitational force on each small sphere due to big sphere is F=GMm/R2.
