The gravitational potential energy is greatest in A while least in D.
When an object is raised through a certain height then its energy increases because work is done against gravity. The energy associated with such a type of object is called gravitational potential energy.
The formula for gravitational potential energy is :
PE = m g h
where,
m is the mass of an object
g is the acceleration due to gravity.
h is the height attained by the object.
When height tends to zero, the gravitational potential energy also becomes zero.
In the given figure, ball A is at the maximum height and ball D is at minimum height. So, potential energy in ball A is maximum and in ball B is least.
Therefore, A > B > C > F > E > D.
