1a)
Fj/s = Fs/j = 6.67 * 10^-11 * 1.90 * 10^27 * 1.99 * 70^30/(778 340 000 *10^3)^2
Fj/s ~ 4.2 * 10^23N
b) Fj/io = Fio/j = 6.67 * 10^-11 * 1.90 * 10^27 * 8.93 * 10^22/(421 800 * 10^3)^2
Fj/io ~ 6.4 * 10^22 N
2) p(N) = m(kg) * g(N/kg)
a) Pmars = 50 * 3.71
Pmars = 185.5N
b) Pterre = 50 * 9.81
Pterre = 490.5N
c) Pjupiter = 50 * 24.79
Pjupiter = 1 239.5N
