    A body's weight is equal to its mass times the acceleration due to gravity. So the body's weitght on planet A is:



    From the data you've been given you can calculate the body's mass. To find it's weight on the moon you then multiply that mass by the moon's value for acceleration due to gravity - call it - I suspect that they give you that value in your text.

    Weight on planet A = 96N
    Gavitational Acc Ga=4.8 m per sq sec
    Mass = 96/4.8 = 20 kg

    Now,
    Gavitational Acc on Moon=1.63 m per sq sec
    Weight on Moon = 20*1.63 = 32.6 N
