If the value of g suddenly becomes twice its value, it will become two times more difficult to pull a heavy object along the floor. Why?

To pull object on the floor we should apply force on it. In this case force is equals to product of mass of that object (m) and g. That is F=gm .Here force is directly proportional to g.. And. m....hence if g becomes double without any change in mass then force also become double. Hence it will become two times more difficult to pull the object on the floor. Rather than for extra information if we thrice the g and twice the mass then required force will be (i.e. F = 3g ✖ 2m = 6 gm =6 F. ) sixth time more.
