    Answer:

    E = 10078.32 J

    Explanation:

    Given that,

    The weight of a window cleaner, F = 839.86 N

    The window cleaner is cleaning windows on the 4th floor of a building at a height of 12 m.

    We need to find the potential energy of the window cleaner. We know that the potential energy of an object is given by :

    E = mgh

    Put values,

    E = 839.86 × 12

    E = 10078.32  J

    So, the window cleaner will have 10078.32  J of potential energy.
