Arrange the objects in order from least to greatest potential energy. Assume that gravity is constant. (Use PE = m × g × h.) Til

Charra [1.4K]

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

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

Explanation :

Formula used :

$P.E=m\times g\times h$

where,

P.E = potential energy

m = mass of an object

g = gravity constant = $9.8m/s^2$

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.

$P.E=15Kg\times 9.8m/s^2\times 3m=441J$

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

$P.E=10Kg\times 9.8m/s^2\times 9m=882J$

(3) 1-kilogram ball located 20 meters.

$P.E=1Kg\times 9.8m/s^2\times 20m=196J$

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

$P.E=25Kg\times 9.8m/s^2\times 2m=490J$

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

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