Question

numercial values of gravitational constant
​

Answer 1

Answer:

Numerical value 6.674 30 x 10-11 m3 kg-1 s-2

Standard uncertainty 0.000 15 x 10-11 m3 kg-1 s-2

Relative standard uncertainty 2.2 x 10-5

Concise form 6.674 30(15) x 10-11 m3 kg-1 s-2

Answer 2

6.674 30 x 10-11 m3 kg-1 s-2

The constant of proportionality in the equation is G - the universal gravitation constant. The value of G was not experimentally determined until nearly a century later (1798) by Lord Henry Cavendish using a torsion balance.
