G (MEANING & UNIT)

#‎Hello‬ ‪#‎BENDING‬ ‪#‎LOVERS‬
MEANING OF G:-
As explained in earlier post about gravity,now we move towards ‪#‎G‬ (gravitatinol constant).
According to Newton's law gravitation,
F=G*m1*m2/d^2
If m1=m2=1kg & d=1 metre,
Then F=G*1*1/1^2
F=G
Newton's gravitational constant G is numerically equal to the force of gravitation b/w 2 objects of unit mass each kept at a unit distance from each other.
UNIT OF G & ITS VALUE:-
Unit of G in S.I. is,
G=F*d^2/m1.m2
Where,
A)m-kg;
B)d-metre;
C)F-newton;
So, G=N*m^2/kg^2
This also written as Nm^2kg^-2.
Value of #G as found experimentally is 6.6734*10^-11 Nm^2/kg^2.
