Derive the relation between g & G

1.	Derive the relation between g & G
Answer» F=GMm/R^2F=mgTherefore comparing 1 and 2 eq. ,GMm/R^2=mgTherefore g=GM/R^2<br>G stands for Newton\'s universal gravitational constant, whereas g stands for the acceleration due to gravity at a certain point.G =\xa06.67300 × 10-11\xa0N.m2.kg-2.\xa0G is a constant throughout space and time.g = 9.8 m.s-2. g is a variable quantity.G is a scalar quantity whereas g is a vector qualtity.\xa0\xa0(According to Newton\'s law of universal gravitation the force of attraction between two bodies is given by F = GMm/r2, where the symbols stand for their usual well known meanings. Also the weight of a body of mass m is F = mg.So mg =\xa0GMm/r2,\xa0or g = GM/r2g is a constant at a given location, which depends upon M and r.)<br>g=( GM)/R^2
