Answer:
C 1.67 × 10-9 N
Explanation:
The magnitude of the gravitational force between two objects is given by:
[tex]F=G\frac{m_1 m_2}{r^2}[/tex]
where
G is the gravitational constant
m1 ,m2 are the masses of the two objects
r is their separation
In this problem, we have:
[tex]m_1 = m_2 = 15.0 kg[/tex]
r = 3.00 m
Substituting into the equation, we find
[tex]F=(6.67\cdot 10^{-11}) \frac{(15)(15)}{3.00^2}=1.67\cdot 10^{-9} N[/tex]
