newton's law of universal gravitation states that every particle in this universe attract every other particle with a force of attraction directly proportional to the product of their masses , inversely proportional to square of distance between them and always acts along the line joining the centres of the two particles
mathematically:
F=G.m1.m2/r^2
G=F.r^2/m1.m2
where G is the constant of proportionality called universal gas constant
m1&m2 masses of the two particles
r distance between two particles
F gravitational force of attraction
unit
G=Nm^2/kg^2 is the si unit that is newton per metre square per kg square
