Question

if the value of g suddenly become twice its value, it will become two time more difficult to pull a heavy object along the floor, why?

Answer 1

hey dude ,
_______________
your answer is ---

we know that ,

Force = mass × gravity ( in respect of earth)

or F = m × g

where ,

•F is force

•m is mass &

•g is the acceleration due to gravity


so, from the above relation
force is directly proportional to gravity g

therefore , when g become double then force (F) also become double , due to this it is very difficult to pull a heavy object along the floor. .

hope it help you

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.
