Question

The potential energy of a girl is maximum

a)Sleeping on the ground
b)Standing
c)Sitting on the ground
d)Sitting on the chair

Note: Reasonable answer will be marked as brainlist!​

Answer 1

1. standing and it depends on the girls height and chairs height

Answer 2

The potential energy of a girl is maximum when she is standing on the ground.

Potential Energy: The energy which is created by an object by virtue of its position which is relative to others, stress within itself, electric charges, etc.

a) Potential energy of a girl is defined by the position of the body in the gravitational field.

b) Formula of Potential energy is:

     PE = M x g x h.

here, h = Height of the body above the ground

        g= Gravitational force

         M = Mass

c) As the girl will be standing on the ground the height will be maximum, hence the potential energy will be maximum.

d) Sometimes the potential energy, in this case, can also be dependent on the height of the chair also.
