    a. the air resistance on each sphere is 1/10mg
    b. when the air resistance on the uppermost sphere is 3/10mg and the air resistance on each of the 4 spheres is 1/20mg

    Is the top sphere fixed in position and are the spheres identical? It might help to draw a diagram, and post your thoughts
