Answer 2

The distance between the two people is  2.934 meters.

The gravitational force between two masses is given by the formula:

$F = G * (m1 * m2) / r^2$

where F is the gravitational force, G is the gravitational constant (approximately $6.67 x 10^-11 N*(m^2)/(kg^2)),$ m1 and m2 are the two masses, and r is the distance between them.

Given that the gravitational force between the two people is 1.48 x 10^-8 N and their masses are 68 kg and 52 kg respectively, we can find the distance r between them by rearranging the formula and plugging in the known values:

$r^2 = G * (m1 * m2) / F$

$r = \sqrt(G * (m1 * m2) / F$)

By substituting the given values in the above equation we get:

r = $\sqrt((6.6710^-11 N(m^2)/(kg^2)) * (68 kg * 52 kg) / (1.48*10^-8 N))$

r =  2.934 m

So the distance between the two people is approximately 2.934 meters.
