Answer 2

Answer:

Here is the answer if you are looking for the person and the experiment -

The value of G was not experimentally determined until nearly a century later (1798) by Lord Henry Cavendish using a torsion balance. Cavendish's apparatus for experimentally determining the value of G involved a light, rigid rod about 2-feet long. Two small lead spheres were attached to the ends of the rod and the rod was suspended by a thin wire.

And here is the answer if you are looking for a formula and a definition-

The gravitational field strength - g - describes the amount of force exerted upon every kilogram of mass in the location surrounding a massive planet, star, or any object (including a person) that has mass.

Formula to find G

Calculate the mean value of g. Alternatively, for each horizontal line obtain the values of L and T and draw a graph with T2 as abscissa and L as ordinate. The graph would be a straight line. By taking a convenient point on the graph, g may be calculated.
