**drwls**, Wednesday, January 12, 2011 at 7:58amThe work done would be

G m1*m2[1/r1 - 1/r2]

r1 = 1.7*10^6 m

r2 = 1.7*10^6 + 2.5*10^4 = 1.725 *10^6 m

Make sure mass is in kg and use the value of G that they provided. The answer should be in Joules.

Be more careful to show units with your numbers.
