We Know That F=ma By Newton's 2nd Law Of Motion. Where F is Force Applied m is mass and a is acceleration of the object.
Now if value of g becomes twice, In RHS a becomes twice i.e. 2x9.8 equals 19.6m/s2
So Friction Becomes Twice As Normal Force On Earth Is Twice
Now Mass Is Constant in all of the universe so for 2nd law to hold Force must also increase by a factor of 2, Hence it becomes two times difficult to pull an object.

aftabchamp:
can i say that weight of object is increase..
Yes Weight becomes twice But Mass Is Constant.
If iy helped yhen plz mark as brainliest
but newton 2nd law says that force directly proportional to mass.. but here mass is constant
The second law states that the acceleration of an object is dependent upon two variables - the net forceacting upon the object and the mass of the object.
the mass is taken or supposed as constant
to solve the question we have assumed it.

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.
