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

As friction is directly proportional to g.
f=mu * normal contact force (in this case, the weight of the object).
If the weight becomes twice, the friction also becomes twice

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.
