Question

The Newton gravitational force   F = Gm₁m₂/r²

        is called an inverse square force. Which of the following would be the reason for it being called that? Input the letter corresponding to the correct answer in the format "X" where X is the letter corresponding to the correct answer choice.

         A.    The formula contains a constant G. This is the reason.

         B.    The Force depends linearly on any one of the masses,

         C.    The Force varies as 1/the distance squared.

         D.    The Force varies as the mass squared.

         E.    There is no such thing as an inverse square force

Answer 1

C. The force varies as 1/(the distance squared)

Gravitational force is inversely proportional to square of the distance between two masses

$F \alpha \frac{1}{r^2}$
