Question
Define gravitational constant. What are the units of gravitational constant?
✓
Answer
The gravitational constant $G$ is numerically equal to the force of gravitation which exists between two bodies of unit masses kept at a unit distance from each other.
$\text{G}=\text{F}\times\frac{\text{d}^2}{\text{m}\times\text{M}}$
units of gravitational constant $= NM^2/kg^2$.
$\text{G}=\text{F}\times\frac{\text{d}^2}{\text{m}\times\text{M}}$
units of gravitational constant $= NM^2/kg^2$.
