How can I find the distance of 2 entities using mass and force?

Question

A sales lady whose mass is 52 kg is doing a product demonstration in front of customers. She

exerts a gravitational force of 7.45 x 10 -8 N on a 57 kg woman who is standing in the front row.

How far is the woman from the sales lady?

Thanks in Advance :)

Answer 1

F = G m1*m2/d ²

G = 6.678106 -11 Nm^2/Kg²

Given m1 =52 Kg , m2 =57 Kg

F= 7.45 x 10 ^-8 N

d²= G 8m1*m2 /F

d² = 6.67*52*57*10^-3 /7.45= 2653.67 * 10^{- 3}

= 2.65

d = 1.63 m = Distance between two
