Answer:
1.308104*10^-8 N (1.31*10^-8 N when rounded)
Explanation:
The mathematical formula for gravitational force is F
=
G
Mm
/r^2 where G is the gravitational constant which is measured 6.674
*10^
−
11
N
(m/kg)
^2.
Since both objects, M and m, have masses of 70kg and the distance r is 5 meters, then we can plug these values into the formula:
F=GMm/r^2
F=(6.674*10^-11)(70)(70)/(5^2)
F=(6.674*10^-11)(4900)/25
F=(3.27026*10^-7)/25
F=1.308104*10^-8
So the gravitational force of attraction between the two objects is 1.308104*10^-8 N.
