Gravity Question?

    Gravity Question??

    Jack is tired of having to use 9.8m/s2 all the time to do his calculations concerning gravity. He wants to use a nice round number 10 m/s2. How much mass would have to be added to the Earth to make this happen? What would the new radius of the Earth be? Assume that the density of the Earth will remain the same. Where could you get the mass needed?

    You know, this would make a good short story...
