given that Earth's surface gravitaitional field strength has a magnitude of 9.80N/kg, determine the distance(as a multiple of Earth's radius re) above the Earth's surface at which the magnitude of the field strength is 3.20N/kg.

3.2 = Gm/r^2 (use earth's mass for m and the universal constant for G)
