Question

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?

Answer 1

1. The weight of an object is defined as the force with which the earth attracts the object. It is given as,
   W = F = mg.
2. The weight of an object depends on the mass of the object and the value of acceleration due to gravity.
3. If the value of g doubles, the force with which the earth attracts the object also becomes twice.
4. Thus, the object becomes twice as heavier, making it harder to be pulled along the floor.
