Question

what is the derivation of SI unit of G ( universal gravitational constant ) ??
plz answer it in mathematical derivation without any spam . If done it will be reported.​​

Answer 1

Answer:

Explanation:

Hi!

We know that F=Gm1.m2/r^2

Taking all the units in SI system we know that

unit of F is N{Newton},unit of mass is Kg,unit of lenght is meter

hence now cross multiplying to get the value of G.

G=F * r^2/Kg ^2

G=N m^2/kg^2

OR

G=N m^2 kg^-2

PS the dimesional analysis is M^-1 L^3 T^-2

Answer 2

Answer:

g =Gravity of Earth. S.I Unit of g is m/sec -Metre per second. If in newton it is N/Kg -newton per kilogrammes..
