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

Explanation:

g is the amount of force by which earth attracts the body.If the value of g become twice the earth will exert twice more force on the body so we will also have to apply twice the force to lift the body.

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.
