The values would be a little different given different densities and stuff, but the math is tedious and I don't fully understand it so I'll just use the defaults.

Drag's results for the first two seem good. As for the third:

50^100^100 =  1.69897 × 10^200

Earth = 5.972 × 10^24 kg

5.972 × 10^24 * 1.69897 × 10^200 = 1.014625e+225 kg

Earth Radius = 6,371,000 m

6,371,000 * 50 = 318,550,000 m

U = (3 G m^2)/(5 r)

Using Wolfram Alpha and I get...1.294 × 10^431 J

According to a local universities website, that is 1.294 × 10^332 Duotrigintillion Joules.
