    Answer:

    Potential energy, P = 500 J

    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

    g is acceleration due to gravity

    P=50\ N\times 10\ m\\\\P=500\ J

    So, the potential energy of 500 J is gained by the box.
