The gravitational force between two point masses ${m_1}$ and ${m_2}$ at separation $r$ is given by $F = k\frac{{{m_1}{m_2}}}{{{r^2}}}$ The constant $k$
Depends on system of units only
Depends on medium between masses only
Depends on both (a)and (b)
Is independent of both (a) and (b)
The gravitational force between two point masses ${m_1}$ and ${m_2}$ at separation $r$ is given by $F = k\frac{{{m_1}{m_2}}}{{{r^2}}}$ The constant $k$
$k$ represents gravitational constant which depends only on the system of units.
