Question

derive an expression for force of attraction between two bodies and then define gravitational constant. please solve it . its urgent

Answer 1

According to Newton's Law of Gravitation the force of attraction between two bodies with masses m and M with distance between them d is ,F =GMmd2
Where G is the gravitational constant defined as the force between two objects with which they attract each other per unit mass and the distance between them being unity .
Now the value of G = 6⋅67×10−8 dyne/cm2=6⋅67×10−11N/m2
