Newtons laws/weight/acceleration/force

    1. The problem statement, all variables and given/known data

    Please help I'm terrible with physics =[

    1) If r is the radius of the Earth, how far above the surface of the Earth would you have to go so that your true weight is one-fourth of what it is on the surface of the Earth?

    a) r
    b) 2r
    c) 3r
    d) 4r

    The only formulas I was given are in the attachment

    Also I need help another question also in the attachment. Sorry if the picture is blurry that's the best I could make it.


    1) For the first question my intuition tells me its 4 but I'm not 100% sure.
    2) I am literally clueless for the second one
