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?....plzz urgent

Answer 1

It's simple.Suppose an object weighs g you can lift it with less effort but if it weighs 2g then more effort will be needed because the weight of the object is constantly increasing therefore it requires more strength.

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.
