The value of gravitational constant, G is
6.7×10−11 Nm2kg−2
G is universal gravitational constant. Its value remains constant everywhere in the universe and gravitational force between bodies m and M separated by distance r is given by:
F=GMmr2
⇒G=Fr2Mm
∴ Units of G are Nm2kg−2
The value of Gravitational constant is 6.7×10−11 Nm2kg−2.
