Note that due to Newton’s 3 rd Law, both masses experience this force (in different directions). What would the value of the gravitational force be in terms of F if: a) the mass of M 1 was doubled doubled b) the mass of M 2 was halved halved c) the mass of M 1 was halved and the mass of M 2 was doubled same d) the masses of M 1 and M 2 was doubled quadrupled e) the separation R was doubled quartered f) the mass of M 1 was doubled and the separation R was doubled
