Question

if the Value of suddenly becomes twice it's Value, it will become two times more difficult to pull a heavy object along the floor. why?

Answer 1

because weight Is directly proportional to the force if we increase weight than force will also increase that is the reason

Answer 2

If the Value of weight suddenly becomes twice it's Value, it will become two times more difficult to pull a heavy object along the floor. This is because weight is the downward force with which earth pulls an object towards its centre. Now we should also note that weight is directly proportional to the gravitational force. So increasing the weight twice will double up the difficulty level to pull an object upwards.
