______NEWTON'S GRAVITATIONAL LAW⭐️⭐️⭐️⭐️⭐️⭐️⭐️

⏩✨Universal law of gravitation states that every object in the Universe attracts every other object with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.....

Answer 2

newton law of gravitation explain that

every body exert force to each other in its centre (centre of mass)

Fg directly proportional m1*m2

Fg inversely proportional to 1/r^2

so

Fg proportional to m1*m2/r^2

on avoiding proportional sign we add a constant G which practically observe and taken

now the equation become

Fg=Gm1*m2/r^2

now unit of G

G=m*a*r*r\m1*m2

write all unit

G=kg*m*s^-2*m^2/kg*kg

G=ms^-2m^2/kg

dimension

G=[M]^1[T]^-2[D]^3

now let us understand few fact

the value of G is not the value of acleration due to gravity

both G and g have different value

g is an acceleration
