Two new ways to measure the gravitational constant

Webwhere F is the magnitude of the gravitational force and G is a proportionality factor called the gravitational constant. G is a universal constant, meaning that it is thought to be the same everywhere in the universe. It has been measured experimentally to be G = 6.673 × 10 − 11 N ⋅ m 2 /kg 2 . WebIt is related to the torque by τ=F (L/2) where L is the length of the small dumbbell. So the gravitational constant can be calculated by Note that, as the mirror turns through an angle θ, the reflected light moves through 2θ. So by reversing the dumbbell an angle of 4θ is measured. Data for this particular apparatus are given in table 1. table 1.
