Answer 1

The gravitational constant, also known as Newton's constant, denoted by the letter G, it is a physical constant involved in the calculation of gravitational effects in Sir Isaac Newton's law of universal gravitation and in Albert Einstein's general theory of relativity. Its measured value is approximately 6.674×10^−11 m³⋅kg^−1⋅s^−2
Henry Cavendish with his Cavendish experiment, performed in 1798 was able to figure out the gravitation constant
