Pluto will have least gravitational potential energy when lifted to a height of 1 m
What is Gravitational potential energy ?
Gravitational potential energy is the energy possessed or acquired by an object due to a change in its position when it is present in a gravitational field.
Gravitation potential energy can be calculated by = m*g*h
where
m = mass of the object /body
g = acceleration due to gravity at that place
h = height of the object
since , mass and height are constant as mass can not be changed , it remain same irrespective of place, hence mass = 30kg and height = 1m
so , the Gravitation potential energy will depend upon gravitational force
Gravitation Potential energy is directly proportional to acceleration due to gravity at that place , hence gravitational potential energy will least at that place where acceleration due to gravity is least which is Pluto having least value of acceleration due to gravity = 0.42 m/[tex]s^{2}[/tex]
