Arrange the objects in order from least to greatest potential energy. assume that gravity is constant. (use pe = m × g × h.) tiles a 15-kilogram stone found at a height of 3 meters10 kilograms of water stored at a height of 9 metersa 1-kilogram ball located 20 meters in the aira box of books weighing 25 kilograms placed on a shelf 2 meters high

Answer : The order of potential energy from least to greatest is,

(3) < (1) < (4) < (2)

Explanation :

Formula used :

where,

P.E = potential energy

m = mass of an object

g = gravity constant =

h = height

Now we have to calculate the potential energy of following options.

(1) Tiles a 15-kilogram stone found at a height of 3 meters.

(2) 10 kilograms of water stored at a height of 9 meters.

(3) 1-kilogram ball located 20 meters.

(4) In the area box of books weighing 25 kilograms placed on a shelf 2 meters high.

From this we conclude that, the order of potential energy from least to greatest is,

(3) < (1) < (4) < (2)

The objects in order from least to greatest potential energy:

Explanation:

Potential energy is an energy of the body due to its position.

m = mas of the body

g = Acceleration due to gravity

h = Height at which body is placed

Potential energy of the stone:

m =  15 kg, h = 3 m , g =

Potential energy of the water:

m =  10 kg, h = 9 m , g =

Potential energy of the ball :

m =  1 kg, h = 20 m , g =

Potential energy of the book :

m =  25 kg, h = 2 m , g =

The potential energies in order from least to greatest :
