The values of proportionality constants in physical relations, such as the universal gravitational constant (G) and Coulomb's constant (k), are determined through meticulous experimental methods. G is noted for being the least precisely known physical constant, with varying levels of precision depending on the experimental approach. In contrast, Coulomb's constant has evolved from an empirically derived value to a precisely calculated one based on other constants. Understanding these constants requires a grasp of the experimental techniques used to measure them and their associated uncertainties.

Which proportionality constants do you have in mind?Syed Ammar said:I wanted to ask how are the values of proportionality constants in physical relations determined. How do we come to know their exact values ? An explanation with an example please...
