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

Every object in the universe exerts gravitational force of attraction on other objects . Stressing on such fact , the heavy object does not get attracted by our body's gravity due to our negligible mass as compared to that of Earth , thus gets attracted by Earth's gravity. If the value of g is twice , the body will get attracted by Earth more efficiently and it is difficult for us to move the heavy body along the floor. Also, the body's g value increases ,and it's gravity poses an attractive force towards us too.

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.
