Q. 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 $k$
A) Depends on system of units only
B) Depends on medium between masses only
C) Depends on both (a) and (b)
D) Is independent of both (a) and (b)
Explanation
(a) $k$ represents gravitational constant which depends only on the system of units
