Answer 2

" Cavendish's aim was not actually to measure the gravitational constant, but rather to measure the earth's density relative to water, through the free precise knowledge of the gravitational interaction. in retrospect, the density that cavandish calculated implies a value for G of 6.754×10–¹¹ M³ kg –¹s-²."
