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

To pull an object along the floor, it is necessary to do work against the force of friction between the object and the surface of the floor. This force of friction is proportional to the weight, mg, of the object. If the value of g becomes twice its value, the weight of the object and hence the force of friction will become double. Therefore, it will become two times more difficult to pull a heavy object along the floor.

Answer 2

$\huge \huge \bf {\: \pmb{ \blue{Answer}}}$

we know that W = m × g we can see that weight is directly proportional to the gravity so, if the g increases twice the mass of an object will increase twice as well , hence it will create more friction so yes it will be 2 times more difficult to pull a heavy object along the floor
