The gravitational force between Susie and Troy is d) [tex]4.9 \cdot 10^{-8}N[/tex]
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 :
[tex]G=6.67\cdot 10^{-11} m^3 kg^{-1}s^{-2}[/tex] is the gravitational constant
m1, m2 are the masses of the two objects
r is the distance between them
In this problem:
[tex]m_1 = 45 kg[/tex] is Susie mass
[tex]m_2 = 65 kg[/tex] is Troy mass
r = 2 m is the distance between them
Substituting into the equation, we find the gravitational force between Susie and Troy:
[tex]F=(6.67\cdot 10^{-11})\frac{(45)(65)}{(2)^2}=4.9\cdot 10^{-8}N[/tex]
