Question

if the value of g suddenly become twice its value its will become 2 times more difficult to pull a heavy object along the floor why

Answer 1

Therefore, 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.......hence if g becomes double without any change in mass then force also become double. Hence it will become 2 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:-
F = 3g × 2m = 6 gm = 6F
Therefore, it is sixth time more.

Answer 2

Answer:

Explanation:

(i) If the value of g becomes double,the force with

which the earth pulls the object i.e weight of

object becomes double.

(ii) As weightincreases,frictional force also increases

while pulling the object

( iii) Hence, it will become two times more difficult to

pull a heavy object along the floor.
