F = GmM/R2
a) if mass of one body is doubled but the distance remains same; the gravitational force becomes twice
b) if  masses of both bodies are doubled but distance remains the same; the gravitational force becomes four times
c) if masses remain same but the distance between bodies is tripled, the gravitational force becomes one-third.
