The gravitational force of attraction between the man and the woman is $2.3\times 10^{-7}~N$.
We can find the gravitational force of attraction $F$ between the man and the woman as: $F = \frac{G~M_1~M_2}{R^2}$ $F = \frac{(6.67\times 10^{-11}~m^3/kg~s^2)(70~kg)(50~kg)}{(1.0~m)^2}$ $F = 2.3\times 10^{-7}~N$ The gravitational force of attraction between the man and the woman is $2.3\times 10^{-7}~N$.
