Answer:
New force = 12 N
Explanation:
The gravitational force between two masses is given by :
[tex]F=\dfrac{Gm_1m_2}{d^2}[/tex]
Where
d is the distance between masses
Initial force, F₁ = 3 B
Initial distance, d₁ = 10 m
Final distance, d₂ = 5 m
According to the above relation,
[tex]\dfrac{F_1}{F_2}=\dfrac{r_2^2}{r_1^2}\\\\F_2=\dfrac{F_1r_1^2}{r_2^2}\\\\F_2=\dfrac{3\times 10^2}{5^2}\\\\F_2=12\ N[/tex]
So, the new force is 12 N.
