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