Two balls, each with a mass of 0.764 kg,
exert a gravitational force of 9.00 × 10−11 N
on each other.

of the universal gravitational constant is
6.673 × 10−11 Nm2/kg2.

According the law of gravitation attraction: F = G M1M2/R2 Thus R = √(GM1M2 / F) = √(6.673 × 10−11 * 0.7642/9.00 × 10−11) = 0.66 m
