    Answer: C: Two times

    Explanation:

    Increase in height would lead to increase in potential energy by that same amount as long as the mass remains constant

    Mass=

    g = acceleration due to gravity

    h = Height

    M*g*10 = M*g * (2*10)

    10mg = 20mg

    Divide both sides by 10mg

    Equals to 2.

    Hence, increase in height by 2 times the original height would lead to twice the increase in potential energy
