Question

4. What happens to the force between two masses if the mass of one object is doubled?

Answer 1

can you please draw a diagram

Answer 2

\[F_1=G\frac{Mm_1}{r^2}\]
if the distance between the masses stays the same, and
\[m_2=2m_1\]
\[F_2=G\frac{Mm_2}{r^2}=G\frac{M(2m_1)}{r^2}=2\Bigg(G\frac{Mm_1}{r^2}\Bigg)=2F_1\]

Doubling the mass of one of the objects doubles the force between them.
