Answer:
Potential energy, P = 500 J
Step-by-step explanation:
We have,
Weight of the box, W = 50 N
Height of the stairs, h = 10 m
It is required to find the potential energy gained by the box. The potential energy is possessed by an object due to its height. The formula of potential energy is given by :
![P=mgh](https://img.qammunity.org/2021/formulas/physics/high-school/7yaja0rknku2dnj2l09w4bywlemq9e7t9c.png)
g is acceleration due to gravity
![P=50\ N* 10\ m\\\\P=500\ J](https://img.qammunity.org/2021/formulas/physics/high-school/z50vm913scdxtiagj66igorjm5utyf6cu4.png)
So, the potential energy of 500 J is gained by the box.
