Determine the distance between two objects, Physics

Assignment Help:

If the distance between two objects, each of mass 'M', is tripled, the force of attraction between the two objects is:

a)  1/2 the original force

b)  1/3 the original force

c)  1/9 the original force

d)  Unchanged

Ans:

If the distance in between 2 objects, each of mass 'M', is tripled, therefore force of attraction among the two objects is 1/9 the original force.
