Newtons' law for Gravitational force  F = G M1 M2 / d²
      M1 and M2 are masses of two bodies and d is the distance between them.

1) As Force is directly proportional to the mass of each object, the force will be doubled.

2)  d is doubled,  Force will become 1/4th  as Force is inversely proportional to the square of distance.
     d is tripled.  Force will become 1/9th as force is inversely proportional to the square of d.

3)  four times.
