    Potential energy lost by 10 N rock will be greater

    Explanation:

    Two rocks of 5N and 10N falls from the same height. Thus they will loose the potential energy.

    The potential energy lost = mass x acceleration due to gravity x height

    The potential energy lost by first 5 N rock = 5 h

    Because weight of rock m g = 5 N

    Similarly, the potential energy lost by 10 N Rock = 10 h

    here weight of rock m g = 10 N

    Thus comparing these two, the potential energy lost by 10 N rock is greater than that of 5 N rock.
