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

1. force = mass and acceleration
in downwards direction it becomes 'g'if the value of g becomes twice its value,it will become 2 times more difficult to pull a heavy object along the floor because as g will increase gravity will pull the object towards it and it will very difficult to pull the object

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.
