Newton's Law of Gravitation says that the magnitude F of the force exerted by a body of mass m on a body of mass M is
F = GmM/r^2

Question

Newton's Law of Gravitation says that the magnitude F of the force exerted by a body of mass m on a body of mass M is
F = GmM/r^2

anonymous · Answer

its derivative dF/dr is (-2GmM)/r^3

anonymous · Answer

What is the meaning of dF/dr?
1-dF/dr represents the amount of force per distance.
2-dF/dr represents the rate of change of the mass with respect to the force.    
3-dF/dr represents the rate of change of the force with respect to the distance between the bodies.
4-dF/dr represents the rate of change of the distance between the bodies with respect to the force.
5-dF/dr represents the rate of change of the mass with respect to the distance between the bodies.

anonymous · Answer

would it be option 3?
3-dF/dr represents the rate of change of the force with respect to the distance between the bodies.

sidsiddhartha · Answer

yes  DF / DR represents a change in the force (DF) with respect to a change in distance (DR)
