Question

An object of mass 5 m is lifted to a height of 5 h above the floor. What is the potential energy the object gained in this process (in the unit of mgh)? The potential change is

Answer 1

Answer:

Potential energy, E = 25 mgh

Explanation:

Given that,

Mass of the object, m = 5 m

It is lifted to a height of, h = 5 h

It is required to find the potential energy gained by the object. It is given by the product of object's mass, acceleration due to gravity and heigh above ground. It is given by :

$E=m\times g\times h$

$E=5\ m\times g\times 5\ h$

E = 25 mgh

So, the potential energy gained by the object is (25 mgh). Hence, this is the required solution.
