Relstion between G and g? |
|
Answer» G-universal law of gravitation.g-acceleration due to gravity. Nueton\'s law of gravitation :- F =GMm/r2 - 1 From nueton\'s second law :- F =mg -2From 1 and 2 :GMm/r2 = mg GM/r2 = gTherefore,g=GM/r G stands for Newton\'s universal gravitational constant where as g stands for acceleratiom due to gravity at a certain point.G=6.7×10^-11 Nm^2/kg^2 where as G is constant. G is a scalar quantity whereas g is a vector quantity. |
