Question

A body of mass m is raised from surface of earth to a height three times the earths radius. The change in potential energy of the body is

Answer 1

HEY MATE,

THE ANSWER OF YOUR QUESTION IS AS FOLLOWS :: -

ANS. => AS PER AS THE POTENTIAL ENERGY OF ANY BODY IS CONCERNED,

THE CHANGE IN POTENTIAL ENERGY IS TOTALLY DEPEND UPON THE PROPORTIONALITY.

THE POTENTIAL ENERGY DEPENDS UPON THREE FACTORS. THEY ARE AS FOLLOWS =

1. 'm' ( MASS )

2. 'g' ( ACCELERATION DUE TO GRAVITY )

3. 'h' ( HEIGHT OF THE OBJECT FROM SURFACE )

POTENTIAL ENERGY IS DIRECTLY PROPORTIONAL TO MASS ACCELERATION DUE TO GRAVITY AND HEIGHT OF THE OBJECT FROM THE SURFACE.

SO THAT, MASS IS CONSTANT EVERYWHERE IN THE UNIVERSE .

BUT, THE VALUE OF 'g' AT A HEIGHT THREE TIMES THE EARTH'S RADIUS FROM SURFACE OF EARTH IS

"" 0 "".

THEREFORE THE SUMMATION OF THE FORMULA OF POTENTIAL ENERGY WILL BE ZERO.

THEREFORE THE POTENTIAL ENERGY OF THE BODY WILL BE ZERO.

HOPE IT WILL HELP YOU.

PLEASE MARK ME AS A BRAINLIST.

I WILL DEFINITELY FOLLOW YOU.
