How would the force of gravity between two masses be affected if the separation distance between them were,assume F2 represents the new force and F1 represents the original force.(a)quadruple the original distance F2/F1= also one-half the original distance F2/F1

Answer 1

proportional to 1/R^2
double r, 1/4 force
triple r, 1/9 force
quadruple r, 1/16 force
five times r , 1/25 force
etc
